Welcome to you r First Tour thr ough t he Function ality of E³ .logic for Electronics By following the steps described below, you can familiarise yourself with main functions of this programme and see how easy it is to create circuit diagrams for electronics. Please read the respective forewords to the individual chapters since they will help you perform the described actions. Information, pertaining to basic operations and the user interface, can be found in the chapter The E³.series User Interface. By the end of this tour, you will have become acquainted with the various functions, which can then be applied to your own design needs. Have fun with this introduction! Generating Proj ects and Sheets Creatin g a New Proj ect With E³.logic , you always work within a project. A project can consist of any number of drawing sheets and additional documents, which are stored in a single file. Start the programme. To create a new project, use the command File -> New
or the corresponding icon
.
Creating a New Sheet The sheet format can be selected directly from the symbol database. Right-click on the folder Untitled in the Project Window Sheet tab and select the command New Sheet... . The sheet name can be changed in this menu and the desired sheet format DINA3 selected. If several sheets already exist in a project, you can control where a sheet is inserted by activating either of the two Insert buttons (insert as first sheet or at the end). The different sheet formats (e.g. DIN A1, A2, A3 and ANSI A, B, C, etc.) are stored in the database with their unique size, layout and sheet header information.
E³.logic

Start-up Guide
Entering Sheet Header Text Labelling the sheet header information takes place in the menu Sheet Properties... , which can be called up with the context menu. The context menu appears after right-clicking on an empty area of the sheet. The text will, depending on your definition, be transferred from the selected sheet to the new sheet. Overwrite the attribute Circuit name with the text 52.334. This number will be entered in the predefined location on the sheet format.
Displaying Placement Help Lines It is possible to place components more easily using placement help lines, which can be switched “on” or “off”. These help lines are drawn on a level (Level 3), that until now, has remained invisible. To make these help lines visible, use the command View -> Level or simply press the key L. In the following menu, level 3 can be activated by either checking the box (clicking on it) or selecting the command Read Configuration and then the file Placement Grid ON from the directory . . . \ dat a\ . .
After closing the menu, the placement help lines will appear thereby making placement easier on the sheet.

Creating an Opera tion Amplifi er Circuit Here the individual steps for creating the following circuit will be explained.
Symbols and Components E³.logic supports both symbol and component-oriented work. What is a symbol? – a neutral circuit element that has not yet been assigned to a concrete component. Symbols can be used in any combination in a device and also assigned text. At a later date, if the device is assigned to a defined component, the symbol within the component will be checked and the symbol text (e.g. pin names) automatically adapted. And what actually is a component? – Simply put, a component has a predefined number of symbols, which have been assigned pin numbers. Components can also be supplied with assigned additional information, e.g. part numbers, description, supplier, price and so forth.

Start-up Guide
Component- oriented Work/Automatic A
ssignment
The advantage with components is that from the very beginning their pin numbers have been checked and the overloading of symbols or the use of incorrect symbols is impossible. Placing a Component’s Elements Select the component LM324 from the Operation A mplifier folder in the Database Window Component tab and place the operation amplifier (first element of the component) by dragging it to the desired location on the sheet. As soon as the element is clicked on in the Database Window, it will be displayed in the Preview Window, so that you can see if you have found the desired symbol. By placing an element of a component, the entire component will be loaded into the drawing and automatically receive a device designation (IC1). In the Project Window Device tab, you have complete control over all of the devices used and their component structure. Heterogeneous components are defined as separate elements (in the example: OPAMPOW and OPAM) in the standard database. This flexibility is why they can be placed at any location and also be separated from one another. The user can, however, define these symbols at anytime as elements in the database.
Placing Symbols In addition to the symbol OPAMPOW, we must now arrange the operation amplifier component’s 3 affiliated symbols without power supplies. Click on the plus “+“ sign in front of the device symbol IC1 in the Project Window Device tab. You now see all of the symbols, which belong to this device. Symbols, which have already been placed in the project, are displayed in blue and those, which have not, in yellow. Drag the next symbol identified in yellow from the Project Window Device tab and position it at the desired location on the sheet. Because the complete component structure is known, the symbol and component identifiers, along with their pins, will be entered on the symbol.
Start-up Guide

E³.logic
Placing Additional Symbols One after the Other Optionally, the symbols to be placed can be selected beforehand and then arranged one after another. Select both remaining OPAM symbols with multi select (press and hold the CTRL key down while clicking on the symbols to be selected), right click on the symbols to call up the context menu and then select the command Place One-by-One . The symbols will now appear one after the other at the cursor position for you to place at the desired location. The placement of both OPAM symbols has to be undone now using the UNDO command ( or the icon
).
Because only unplaced elements can be selected and placed, this prevents a device element from being used twice.
Exchanging Pins and Gates The pin assignment can be changed if required. Right-click on pin 5 to call up its context menu and enter 10 as the value for the Text in the Text Properties… . By changing pin 5 to 10, all other pins in this gate will be automatically adapted (swapping gates). Incorrect assignments are and will be ignored.message For example, if you try exchanging the input pinspin 9 and 10, this will berecognized ignored and a corresponding appears. Creating the Sub-circuit The operation amplifier circuit can now be created. Select the component PT10 from the Potentiometer folder and the resistor 10K*S1206 from the Resistor folder in the Database Window Component tab and place these as pictured at right. Select the GND symbol from the Signa l c arrying folder in the Misc tab and arrange it underneath the resistor.

Conne cting Component Eleme nts To draw connections, use the pin’s context menu and select Connection . You can also optionally use the
icon or the key C.
While connecting, corners can be defined by clicking the left mouse button. The connection will be closed once the desired connect point has been reached. With the right mouse button, you receive additional options. Another option is to activate the connection mode by double-clicking on the icon when routing. Notice how the cursor changes. As soon as the cursor is positioned over a possible connect point or connect line, where it can be connected, its shape changes again. By clicking the left mouse button, you can begin drawing the connection. If corners are required in the connection, these can also be defined by a mouse click. Once you move the mouse, you can see immediately how the connection is drawn and how corners are generated automatically by the programme. If the cursor is positioned over another possible connect point, its form changes again. Simply click the mouse to close a connection. After the subcircuit has been connected, press the Esc key to terminate the connection mode. Copying a Sub- circui t Because this amplifier circuit is required three times, mark the previously drawn sub-circuit by pressing the left mouse button and dragging a rectangle around it. If you do not require all of the objects or have selected too many, press the Shift key and use the mouse to select any missing parts that have to be added or to deactivate too many selected parts. Press the icon in the symbol toolbar or use the well-known Windows key combination Ctrl/C for copying. With it, the selected objects will be adopted in the clipboard and can then be inserted with the combination Ctrl/V .
icon or the key
Place the copied parts as shown in the figure. Also when copying, like with inserting subcircuits, please observe that no device designation has been used twice or that existing devices are not overcrowded. To receive an overview of the devices, which have already been used, open the Device tab in the Project Window. All devices are listed there in a tree structure and sorted alphabetically by their device designations. When copying, the physical pin assignment will be transferred to the new sub-circuit. This can be recognized byIC2 theand pin assignment on the operation amplifier symbols. This automatically results in two new devices, IC3. To assign the OPAM gates from IC2 and IC3 to the device IC1, right-click on the text node IC2 and enter the text IC1 in the context menu’s Text Properties... . This assignment can also take place in the context menu’s Symbol Properties... .
Start-up Guide

E³.logic
The following warning points out that the pin assignment will be adapted accordingly after making modifications.
Change the pin assignment on the other OPAM gates by replacing the text IC3 with IC1 in the Text Properties... .
Handling Conne ctors Placing a Conne ctor’s Master Symbol and Individual Pins Now we have to search for an appropriate connector in the component database. Select the CANNON25-M connector from the Connecter folder in the Database Window Component tab. For the power supply, select the connector pins 1-3 (press and hold the Shift key) and place them via Drag&Drop + pressing the Ctrl key in the upper left portion of the sheet.
This results in the connector being automatically adopted into the drawing, receiving a unique device designation ST1 as well as being displayed in the Project Window Device tab. Additional pins can now be selected and placed from the Project Window Device tab. Simply drag the yellow-coloured pins to the desired location on the sheet. First we have to place the 4 inputs: select the connector pins 10-13 collectively as a group (Shift key) and arrange them in the drawing. Then we have to do the same with the 4 outputs. Select connector pins 2023 and place them beneath the inputs. These can also be mirrored on the Y-axis during placement using the context menu. For documentation purposes, right-click on the connector ST1 in the Device tab to call up its context menu and then Place the connector’s Master Symbol to the left of the connector pins. The symbol can also be rotated during placement using its context menu.

Start-up Guide
As si gn in g Sign als Now we have to assign signals to the connector pins. Select any connector pin in the affiliated context menu’s Device Properties... . The individual pins can be assigned their signals in the Signal tab in the following dialogue. There are also signal lists, e.g. in the form U1..U4 (see illustration), which are extremely helpful. The pins should be assigned as follows: pins 1-3 will be assigned power supply signals (+12V, -12V and GND); the input pins 10-13 assigned the signals U1..U4 and the output pins (pins 20-23) the signals UA1..UA4.
Ar rangi ng and Co nn ect in g Sheet Referenc es After assigning the signals, place sheet reference symbols on the 3 power supply pins. Select the reference symbol SOURCE_AUTO from the Signalreference folder in the Database Window Misc tab and position it to the right of each of the power supply pins via Drag&Drop . The connector pins must now be connected to the sheet references. The connect lines can be placed individually but don’t have to be. Here you can use Au to co nn ect Ins id e Area.

This command automatically connects all connect points lying next to each other in a defined area, that have not yet been connected. If connections are already contained in the area, these will also be edited. This command can be activated using Insert -> Autoconnect -> Inside Area Horizontal or with the icon. Drag a rectangle around the connector pins and sheet reference symbols. After releasing the mouse button, the connect lines will be inserted. Conne ction Prope rties/La yout Parame ters for Routing Circuit Boards You can easily check these connections by right-clicking on one and selecting the command Connection Properties... from the context menu. In this menu, all connection properties can be viewed or changed. Click on the tab Layout Parameter , so you can find the template for routing the circuit board.
Copying a Sub- circui t The resistor component also has to be placed on the OPAMPOW symbol and connected. Select an already connected OPAM sub-circuit by dragging a rectangle around it with the left mouse button. To deselect the OPAM symbol, use the Shift key and press the left mouse button. Now copy the sub-circuit with
or
the key combination Ctrl/C and place it close to but not directly on the OPAMPOW symbol using or the key combination Ctrl/V .

Start-up Guide
Press the button to display open connect lines in yellow (the colour depends on the colour setting defined in Database Editor nd mode: Format -> C olou r Definit ions … -> 2 Highlight ). To move the OPAMPOW symbol correctly call up the Settings menu and activate the Conne ction -> Allow inserting symb ol in connection option. Now move the OPAMPOW so that the pins are automatically connected to the sub-circuit. A symbol can also be inserted directly on a connect line without having to delete the connection.
As si gn in g Sign als and Con necti ng Sheet Ref erenc es Call up the OPAMPOW symbol’s context menu and select Device Properties... . Here the pins will be assigned their signals in the Signal tab.
The sheet references symbols must also be arranged on the power supply symbol OPAMPOW. Select the reference symbol DESTINATION_AUTO from the Signalreference folder in the Database Window Misc tab and position it via Drag&Drop as shown in the figure (the symbols can also be rotated or mirrored using the context menu).

After connecting the power supply pins with the sheet references, the cross-references are automatically calculated and displayed.
Dynamic Signal Logic Lines Signals will now be assigned to the other operation amplifier symbols in the Device Properties’ Signal tab. Assign the respective inputs the signals U2..U4 and the corresponding outputs the signals UA2..UA4, i.e. the inputs 10, 5 and 12 will be assigned signals U2, U3 and U4, the outputs 8, 7and 14 will be assigned the signals UA2, UA3 and UA4. After assigning the signals, the signal logic lines will be displayed automatically.

Displaying Connector
Text
So as to have a better overview when placing several connector pins, the component code is only displayed on the first pin and it is switched off for the rest of the pins. Prior to moving the individual connector pins to a position corresponding with their dynamic logic lines, we have to switch on (make visible) the desired text nodes.
Mark the connector contacts of connector ST1 (multi select) and call up the menu Symbol Properties... . Here you see all of the text and attributes, which belong to the selected symbols. The box in front of each attribute determines whether the attribute will be displayed or not. By checking (clicking on) the box in front of the Device Designation and Component Code , this text will be displayed for all individual connector pins. Afterwards, move the connector pins according to their signal logic lines via Drag&Drop . To complete the sub-circuit, we must still add the missing connect lines. Connect the symbols using the command Insert > Autoconnect -> Inside Area that was previously used in another section.
Start-up Guide

E³.logic
Completing the Basic Circuit Verifying the Power Supply After all of the connections in the circuit have been connected, the power supply must be verified. Select the zoom area, which contains the power supply connector pins. Because the GND sheet reference signal contains no reference to another sheet reference (all GND pins are connected in the circuit with the GND symbol), delete the SOURCE symbol and replace it with a GND symbol.
Searching in the Project Trying to find a specific element in a large drawing can be very time-consuming. E³.logic , however, makes this task quite easy. Simply define the information to be searched and with the push of a button, the corresponding page in the drawing will be opened and the desired element highlighted. Start the command with Edit -> Search... , or by pressing the icon or the F3 function key. Enter the object type to be searched and its value in the menu. For example, enter the object Signal in the field Type and the signal +12V in the field Value. With this, all pins and connect lines will be searched, which have the signal +12V. The search results will be displayed in the Output Window and by doubleclicking on the desired line, you jump directly to the corresponding sheet, on which the object searched is marked. This allows you to find information quickly in your plans as well as always having an overview of your drawing. To remove the highlighting from the marked object(s), select the command Edit -> Reset Highlight or press Shift and the F3 function key.

Start-up Guide
Navigating i n t he Project With the navigational possibilities in E³.CADdy profesional , you can quickly jump to a desired location. Click the right mouse button on the crossreference text and select the command Jump . The sheet, on which the cross-reference is displayed, will open automatically and the symbol highlighted. Another way to navigate in the project is by using the “on-line parts list“ in the Project Window Device tab. Double-click on any symbol in the device tree, which has already been placed, and you will jump directly to the corresponding symbol.
Modifying an Existing Drawing It’s crucial that the user be able to modify a drawing quickly, easily and reliably (proofed). Modifications are displayed automatically in all representations of an object and can be carried out at the appropriate location by the user. One such example is to move connected symbols. This can be done quickly and intelligently with E³.logic . Select, for example, a potential symbol and move it while pressing the left mouse button. You'll notice that the connection line, connected to the symbol, moves automatically as well. Also, when moving a symbol, the system constantly checks to see whether the new position is allowed and if the connection line can be drawn without conflicting with any other elements. When a symbol from connection, the connection closes automatically, provided that thedeleting attributes assigned to an theexisting connection, permit it. Otherwise, the connections will remain 'open'. Delete a resistor by selecting the symbol and pressing the Del key. The symbol will be deleted and the connection closed. To undo this delete procedure, use the UNDO command.

As si gn in g and Chang in g A tt ri butes Now we have to assign attributes to the devices. Call up one of the OPAM symbols’ context menus and select Devic e Properties... . Enter the text OPCircuit 1 as the attribute BAUGRUPPE (ASSEMBLY) in the dialogue. By clicking on the box in front of the attribute, the attribute BAUGRUPPE will or will not be displayed.
There are several ways to change the attribute text. One way is to modify the attribute in the Device Properties . Also, if the attribute is displayed as text in the plan, this can be modified by simply changing the text. Right-click on the attribute text OP-Circuit 1, select Text Properties… and change the text there. This results in the attribute being changed directly.

Start-up Guide
Ad di ng Text and Graph ic s Of course, free text and graphics (which have no electrical relevance) can be added to a circuit diagram. E³.logic also offers multiple possibilities here. The power supply pins should be enclosed by a rectangle and completed by adding the appropriate text. Select the icon from the symbol toolbar in the lower left-hand corner. The rectangle will be displayed at the cursor position. Click on a corner of the rectangle and while pressing the left mouse button, drag a rectangle around the area to be enclosed. To change the line type, click on the rectangle and select the line type “dashed“ from the symbol toolbar.
To add free text, use the command Insert -> Text... or the icon from the symbol toolbar. Enter the text (also multi line) in the input menu and define the text parameters (e.g. typeface and text size). After closing the menu with OK, the text will appear at the cursor position, where it can now be placed anywhere on the sheet with a mouse click.
The text size can be changed at anytime in the Text Properties menu or by using the corresponding field .
Text can also be accessed through the Text Database by pressing the key in the input menu. The text, which has already been placed, will be translated online when changing the language (Tools ->Se tti ngs -> General -> Language ). Up to five languages can be defined.
Start-up Guide
17
E³.logic
When all texts (and also attributes) are entered through the text database, the complete drawing can quickly and easily be switched to another language (or several languages).
Verifying the Circuit With Tools -> Verify , you can check the small sub-circuit that you have created. If any errors or warnings are found, they will be listed in the Output Window.
Explanation of the errors listed: All pins in E³.logic must have a signal. Because, however, only the three power supply pins and the four input and output pins of the 25 pin connector have been assigned signals, the remaining individual pins will be announced (listed) in the Output Window, e.g. ST1: 25 has no signal. Assign all connector pins, which do not have a signal, the signal **NC** in the Device Properties... . Also assign pin 26 and 27 to the **NC** signal.
When copying the OPAM sub-circuits (see Copying Sub-circuits), the devices IC2 and IC3 are created automatically. Since their OPAM gates have been assigned to device IC1, they are no longer needed in the project. To remove all unnecessary objects from the project, right-click on the project name in the Project Window Device tab to call up the context menu and select Purge Unused Objects .
After performing the above-mentioned modifications, select Tools -> Ve rif y once again; you will see that no errors or warnings are listed in the Output Window.

Generating Lists, Table of Contents and Documents Parts and Connection Lis ts Information contained in the project can be output to any document, list and/or file. In addition to the already predefined documents, such as Table of Contents, Parts List (BOM), Connection List, and so on, the integrated Visual Basic programming interface allows reports to be generated in any format, as well as, the ability to interface with other programmes. The COM-interface can load or add data to the drawing using any programming language. Several lists are predefined and can be output directly in Excel, Access or Word Format, provided that they are installed on your PC. You can, for example, create the Parts List as an Excel file. These possibilities will be described in greater detail in the next chapter Modular Design. Cover Sheet with Table of Contents Likewise, it’s possible to create a cover sheet automatically with a table of contents using the command Ad d-ons -> E³.seri es Docu ment s -> Create Cover sheet. We will now add bit-map graphics to the cover sheet, e.g. your firm’s logo. Start the command File -> Import -> Image... and select the desired figure from the appropriate directory (*. j pg). You can then place the figure wherever you like on the sheet. Naturally, you can also change the size of the figure after placing it on the sheet. A mechanical drawing can also be entered on the cover sheet. This can be done quickly and quite easily with the DWG/DXF import command. Start the command File -> Impor t -> DWG/DXF... and select the DXF file from the appropriate directory. A menu appears, in which you can specify the size and position of the mechanical drawing. To change the size of the drawing, click on the “handle” in the upper right-hand corner of the grey rectangle, and then move it to the desired location on the sheet. If you desire an exact scale and placement, these values can be entered directly in the menu.

Embedding Add itional Documents Relevant information can be added as files to an E³.logic project. These could include documents from other applications, such as instruction manuals, evaluation tables and so forth. E³.logic allows you to integrate these documents into the project. The only prerequisite is that the applications used to create these documents are compatible with Active-X (e.g., Microsoft Word, Excel). The following example works only if you have Microsoft Word installed on your computer. Start the command Insert -> New Object... . A menu appears, in which all Active-X compatible programmes installed on your computer are listed. Because you are opening an already existing document, select Create from Fil e and click on the command Browse... . Select a file. Microsoft Word will now be started inside E³.logic with the selected document. The E³.logic user interface changes to the Word user interface, where you can edit the text. As soon as a sheet in E³.logic is activated, you automatically return to the E³.logic user interface. The Word document, embedded in your project, will also be saved. The file, which you selected, is still in its srcinal form and hasn’t been changed by any actions within E³.logic .
Output Files Exporting Sub-circuits Change back to the sheet with the operation amplifier circuit. This subcircuit will be exported in a file. Mark the entire sub-circuit by drawing a rectangle around the area while pressing the left mouse button. Select File -> Export -> Drawi ng... and enter the File name 4XOPV. e3p and then Save (the pushbutton Selection must be activated in the dialogue). This circuit can now be reused in other circuit diagrams (see Hierarchical Design).

In the following exercise, the underlying Operational Amplifier circuit will be added to the block on the left side of the diagram and 4 LED blocks and their underlying sub-circuits added to the right, so that it looks like the following:
Overview of the Circuit Explanation of the procedures used to create the circuit pictured above: The Operational Amplifier circuit, shown on the left side of this drawing, is already depicted by a hierarchical block with corresponding module interfaces. However, the underlying circuit is missing. The corresponding module circuit is available in the central module directory and will be integrated into the existing hierarchical block. The sensor modules, arranged in the middle of the diagram, have already been placed, along with their hierarchical drawings and are also available as module types in central module directory. The right-hand portion is missing the 4 LED sub-circuits. First one will be designed as a hierarchical module, saved and then reused for the other three.

E³.logic
Generating a Hierarchic al Module In this example, a LED sub-circuit will be designed as a hierarchical module.
Placing and Modifying a Bloc k Symbol A hierarchical module is represented by a block symbol. These block symbols (size and text nodes) are defined in the database. By selecting Insert -> Block... , you can place the predefined, empty block symbol in the circuit diagram. The block symbol will appear at the cursor position and can then be moved to the desired location. Click the left mouse button to place the block. The block’s size can be modified, as required, by first clicking on the block to display the blocks “handles” and then by clicking on one of the handles and dragging it to modify the size.
Ad di ng Modu le Inter fac es (Por ts ) To connect hierarchical modules, module interfaces (module ports) are required. These are positioned along the edge of the block. In this example, 2 module ports (for IN and OUT) must be added. Select the symbol MPORT from the Module Port folder in the Misc tab of the Database Windowand place it using Drag&Drop onto the edge of the block and the Module Port dialogue will be displayed In the Module Port dialogue, the names of the module ports are entered. Enter the names of the module ports (IN and OUT) and press OK. Note : Module ports are added automatically according to the number of port names entered and the spacing between the ports is based on the Distance setting at the bottom of the dialogue. The module ports can only be placed and moved along the edge of the block. Position both ports on the block’s contour as shown.
E³.logic

Start-up Guide
Status Flag A status flag is displayed at the hierarchical block’s upper right-hand corner, showing that 2 module ports must still be added to the underlying circuit. To go (jump) into the hierarchical block, right-click anywhere within the block and select the Into hiera rchy in new window command from the block’s context menu. The first sheet of the hierarchical level, on which the LED circuit will be generated, is created automatically.
Generating the LED Circuit You are now going to create the LED circuit. Select the resistor type 10K*00009 from the Resistor folder in the Component tab of the Database Window and place it, as shown, using Drag&Drop . In the Diode folder, select the component LD*50001, right-click and select the Place command on the associated context menu. Drag the symbol onto the sheet and press the right mouse button. Select the command Rotate or Mirror from the context menu and then place the diode.

Navigating from the Hie rarchical Port to th e Block When module ports are placed, the cross-references are entered automatically and the status flag, on the hierarchical block, is updated accordingly. To verify the navigational functions of E³.logic , right-click on the cross-reference text of the IN module port and select the Jump command. The sheet, to which the cross-reference refers, will open automatically and the corresponding module port on the hierarchical block highlighted. Because both module ports have been placed, the status flag on the hierarchical block is no longer displayed (possibly after pressing the refresh function key F5). Furthermore, the sheet references will be determined and entered automatically on the ports. Now the LED Circuit hierarchical module can be connected with the rest of the circuit.
Labelling the Hierarchical Module By right-clicking on the text in the bottom left corner of the block, select Text Prop erties and change the Module designation to LED1 and enter LED for the Module type .

Ad di ng Text and Graph ic s Additional Text and Graphics can be added to complete the hierarchical block symbol. Use the Insert -> Text... command or the icon on the Text Format toolbar to enter free text, i.e. text that is not associated with a symbol or component. Enter the text in the Insert Text dialogue and define the text parameters, e.g. typeface and text size. (Multi-line text can be added using Ctrl + Enter ) Select OK and the text will appear at the cursor position, where it can now be placed anywhere on the block with a mouse click. Text can also be accessed through the Text Database by pressing the key in the input menu. The text, which has already been placed, will be translated online when changing the language (Tools ->Setting s -> Genera l -> Language ). Up to five languages can be defined. When all texts (and also attributes) are entered through the text database, the complete drawing can quickly and easily be switched to another language (or several languages). Additionally, by using the graphics commands, graphics can be added to the hierarchical block, to indicate the functionality of the underlying circuit. An alternative, and often simpler method, is to select an existing symbol in the database and place it as a graphic. In this example, select the component LD*50001 from the Diode folder in the Component tab of the Database Window,context right-click and select the Place as Graphic command on the associated menu. After placement the symbol graphic can be resized and moved, as required, on the hierarchical block symbol All graphic objects can be connected to other elements. In this case, using the Shift key, select the hierarchical block, the graphic symbol and any free text that was added, and then select Group Graphicc ommand
.
Saving the Hierarchical Module Finally, the hierarchical module can be saved so that it can be re-used in other circuits. Right-click on the hierarchical block symbol, select the command Export Module Type… on the context menu and select Save. This will result in the module file LED.e3m being created in the current directory.

Importing a Hierarchical Module To reuse (place) the LED circuit as a module, select the Insert -> Block... command, select the Create from Fil e radio button on the dialogue and select the previously saved LED hierarchical module (LED.e3m). The module block outline is displayed at the cursor position and can then be placed at the desired position in the circuit diagram. If the Device Designation of a module being imported is the same as one already in the project (e.g. R1), the name of the module being imported will be automatically modified (e.g. R2). This ensures that all device designations are uniquely identified in the project. Signals are modified in the same manner. If a signal name is already used in the project, a systemdefined signal (#n) will be generated automatically for the module. Exception: power supply signals are always used. After the 4 LED modules have been placed, connect their ports with the rest of the circuit.
Integra ting an Existing Single Level Sub-circuit Status Flag The hierarchical block, for the Operational Amplifier circuit (left), along with its module interfaces (module ports) has already been defined by another user and corresponding connections added. In the upper right-hand corner of the hierarchical block, a status flag is displayed showing that the underlying circuit is still missing 11 module ports. To go into the hierarchical block, rightclick on the the Into hierarchy in block ne w and windselect ow command on the block’s context menu.

Overview of the Circuit Explanation of the procedures used to create the circuit pictured below:
The operation amplifier circuit, shown in the left-hand portion of this drawing, is already symbolized by a hierarchical block with corresponding module interfaces, however, the underlying circuit is missing. The corresponding module type is available in the central module directory and will now be integrated into the existing hierarchical block. The sensor modules, arranged in the middle of the diagram, have already been placed and are also available as module types in the central module directory. The right-hand portion is missing the 4 LED sub-circuits. Because there is no corresponding module type contained in the module directory, a circuit module type must be created in E³.logic and the affiliated layout module type in CADES-G/BLS.

Using Predefined Module Types To simplify matters, this example uses predefined module types, which already exist. Beginning with every new design, it should be clarified whether module types srcinating from other projects are available or not. Status Flag The hierarchical block, for the Operational Amplifier circuit (left), along with its module interfaces (module ports) has already been defined by another user and corresponding connections added. In the upper right-hand corner of the hierarchical block, a status flag is displayed showing that the underlying circuit is still missing 11 module ports.

Welcome to your First Tour throug h the crea tion o f Symbols, Models and C ompo nents u sing E³.logic’ s Database Editor Previously, you have worked only with components and symbols that already existed in the database. In the following chapter we will show you how to create your own symbols, models and components using the Database Editor (DBE) in E³.logic . General Information What is a symb ol? A symbol is a circuit element that can be assigned to a component. As many components use the same circuit elements, symbols only have to be created once in the database. They can be combined in any combination and then used in different components. What is a component? Components exist as physical devices. A device is a component that is used in a project and is identified by a device designation. Components are stored in the database, ready for use in a project, and contain • •
one or more symbols for creating the circuit diagram, as well as a model, that defines its physical description, and is used for displaying on the circuit board.
E³.series automatically manages all of a device’s elements. Additional information can also be defined for components, such as their part number, description, manufacturer, price and much more. Creating Components To create a Component, first open a new project using the command File -> Newor the
icon.
Symbols, models and components are created using the Database Editor mode. This is a special mode within E³.logic , in which components, housing types and symbols as well as standard definitions for attributes, text and colours can be defined in the database. Since several users can have simultaneous access to these databases (configuration, component and symbol), any modifications made will immediately affect all other users. Different functionality is provided in Database Editor mode and each user has his own working area for the creation of symbols and components. To toggle back and forth between Project and Database Editor mode, for example, when you want to use part of an existing drawing for a new symbol, press the icon. To switch back to the Database Editor mode, press the button again.

7.
Create the Circuit Diagram Symbols • To create symbols, draw the symbol graphics, arrange the pins for the electrical connections and define the attributes. • Symbols can be combined in any combination and then used in different components. Define the Layers/Technologies • This step is necessary only once when starting to work with the Database Editor, only the layer Al l is interpreted. Define the Drill Holes • Describe the diameter/tolerance combinations, which can be used later for the pins. • This step is also only necessary when you start working with the database. Later, only then if new combinations are necessary because of the addition of new component body types with new pin sizes. PinDesign/PadStack • Pad symbols, like other symbols, are created with the DBE and stored in the symbol database. • The pad stacks use a layer from the Layer Table and link it with a pad symbol. A pad stack consists of (later on) several such value pairs and describe a "pad symbol stack". • A pad stack and technology are combined to define a typical pin design, which can then be used to describe the different pins in a component. Supplies • Define the supplies using standard signals. Create the Model • A model contains graphics, restricted areas if necessary,... also pins along with their position, drill, pin code and pin design. • A model can then be used for many different components. Create the Comp onent • Components contain normal symbols (circuits, gates, ...) with pins • and one model with all the physical pins. When creating a component, the symbolic (circuit) pins must also be assigned to the corresponding physical (model) pins.

Creatin g a New Symb ol General Information The fastest way to create a new symbol is to use a similar, existing, symbol as a template, modify it as required, and then save it under a new name. For practice, however, we will create a completely new symbol without using a template: NAND_FS. To do this, the following steps are necessary: • • • •
draw the symbol graphics define the pins for the electrical connections add the required text type text nodes define the attributes
To create a new symbol, start the Database Editor. The easiest way to do so is to right-click in the grey column heading, in the upper portion of the Database Window and select the command New Symbol from the displayed context menu. This switches the user to Database Editor mode and opens a drawing window for creating the new symbol.
Settings The size of the sheet, displayed in the drawing window, depends on the size selected in Tools -> Settings ... -> Database Editor -> Symbol . The grid and rulers can be displayed by selecting the View -> Rulers or View -> Grid commands or by pressing the corresponding buttons
or
.
The grid points can be used to help draw the symbol. The grid spacing is defined in Tools -> Settings ... -> Database Editor -> Symbol . Note: The displayed grid can be set to a different spacing to the working grid. The cross in the middle of the drawing area displays the symbol’s srcin. This will be used as the lower left-hand corner of the symbol.
E³.logic

Start-up Guide
Graphics To draw the graphics, select the Rectangle button on the Database Graphictoolbar and draw a square with a side length of 16 mm . This is equivalent to 16 grid points because the standard grid setting is defined as 1 mm in the Database Editor. Next draw the circle, as in the figure, using the grid points as a guide. The line’s thickness, colour, level and style can be defined using the Graphic toolbar or for selected elements, they can be changed in the Graphic Properties... context menu. The lines for both inputs do not have to be drawn because they will be generated automatically when adding the symbol’s pins. Alternatively, the complete symbol graphics can also be generated by dragging an existing symbol from the Database Window’s symbol tree view.
The Space Requirement
button on the Database Symbol toolbar
is used to display the new symbol’s space requirement. The button is used to change the symbol’s space requirement so that it encompasses all of the symbols graphics. The symbol’s srcin can be moved to another position by selecting the
button.
Pins The pins will be defined next. E³.series recognises electrical pins, including their preferred connection direction. The Database Symbol Node toolbar contains a drop-down list of the pin symbols with their graphics, text and user-defined connection directions.
Start-up Guide
63
E³.logic
Both inputs are connected from the left side. Select the symbol Node - from left in the Node Symbol drop-down list and place it twice as shown in the figure using the Single Node button. The graphic lines for connecting will be generated automatically. The connection for the output pin will be defined in the same way except the connection direction is Node - from ri ght .
The pin name text node refers to the corresponding pin. Pins and pin name text nodes can be placed individually, so when this method is used, care must be taken to ensure that the pin name and pin have the same sequence number. Click on the Node Order button, on the Symbol Node toolbar, to display the pin sequence (command: Edit -> Order D efinit ion -> Node). The Node Order Definition menu appears. To change the order of the nodes, check the desired option and click on the nodes in the correct "new" order afterwards. Press the key to terminate the command.
Text Now add the text nodes for the symbol. Text nodes can be added individually by using the Database Symbol Text toolbar. However, a standard text template, containing the required text nodes, already exists for this: TEXT_L. It can be found in the Template folder in the Misc tab of the Database Window. Place the template using either Drag & Drop or Place in the context menu.
In the drawing, green crosses represent the location of the text nodes. The actual values will be entered automatically by E³.series and displayed using the text parameters defined for the node.

To see what the text nodes represent, simply switch the display mode by pressing the Display Text Type button, on the Database Symbol Text toolbar.
Lastly, replace the first text node Free Symbo l t ext (Type 14) by the "&" character above the 4 text nodes already placed. To do this, on the Symbol Text toolbar, select the text type as Text - fix from the drop-down list, select the Symbol Textbutton enter the “&” character in the text field of the Insert Text dialogue.

On the Symbol Prope rties dialogue, enter the Name of the new symbol as NAND_FS, select “Logic ” from the drop-down list in the Class field (this defines the folder, in which the symbol is stored).
To save the symbol to the database, right-click anywhere on the drawing sheet and select Save to Database on the displayed menu (or use the File -> Save to Database command). When finished working with the Database Editor, select the command Tools -> Stop Database Editor to switch you back to the Project mode. If the new symbol does not display in the Database Window, update the database view by using Function key F5 in the Database Window and now the new symbol can be used in the circuit diagram. If other users are using the same database the new symbol is also ready for them to use.

To create a new model, start the Database Editor. The quickest way to do this is to right-click in the grey column heading, in the upper portion of the Database Window and select the command New Model from the displayed context menu. This switches the user to Database Editor mode and opens a drawing window for creating the new model.
Settings The size of the sheet displayed in the drawing window depends on the size selected in Tools -> Settings ... -> Database Editor -> Model . The grid and rulers can be displayed by selecting the View -> Rulers or View -> Grid commands, or by pressing the corresponding buttons

The grid points can be used to help draw the model. The grid spacing is defined in Tools -> Settings ... -> Database Editor -> Model . For this example, in the Settings the Measurement Unit s for the Database Edito r should be in Inches , and the Working Units for the model creation should be defined in the Model tab as 0.025". The Grid View Points should be defined as 0.025" and the Rulers as 0.005". Verify these values and correct if necessary. The srcin of the new model will appear in the centre of the worksheet and later serve as the model’s centre.

Graphics Now draw the graphics for the placement outline or silkscreen. Select the icon in the Graphic toolbar and draw a rectangle, which extends 3 grid points horizontally from the model’s srcin in each direction and 7 grid points vertically from the srcin in both directions. Therefore, the rectangle’s dimensions are 150 mil by 350 mil (= 0.15" by 0.35"), because the spacing between grid points is defined as 25 mil (= 0.025"). Next draw the small square, which identifies pin 1 in the figure. Always use the grid points as a guide. The line thickness, colour, level and style can be defined using the Graphic toolbar or for selected elements, they can be changed in the Graphic Properties... context menu. The rectangle and the square should be placed on Level 24. This level can then be selected when creating the placement outline and/or silkscreen.
To place the graphics on Level 24, select the graphics, by clicking on each in turn with the SHIFT key pressed, (or by dragging a rectangle around them), then right-click and select Graphic Properties on the displayed menu. On the Graphic Properties dialogue change the Level to 24. CIM-TEAM has proposed the following level definitions: • •

define the attributes Component Wizard and structure using the edit the component structure assign the schema pins to the model pins
To create a new component, start the Database Editor. The quickest way to do this is to right-click in the grey column heading, in the upper portion of the Database Window and select the command New Component from the displayed context menu. This switches the user to Database Editor mode and starts the Component Wizard.

Component Wizard The Component Wizard assists in creating a new component, i.e. it leads you through the process of creating a new component. The user can specify the Name and Type of component as well as any additional global parameters in the Identification Dialogue. In this example, we are going to create a standard device by selecting Type: Standard device . Additional information must still be entered: •
•
•
Enter the Name of the component as 7400-SMD. If a component with this name already exists in the database, it will be rejected. Select the Device letter code IC from the drop-down list (or a new one can be entered directly). This letter code is used as the prefix for the Device Designation, which identifies the component when placed in a drawing. Select the Supply Type VCC.
Click Next. This switches to the next page of the Component Wizard...the Properties dialogue. Enter the component-specific attributes/properties in the Properties dialogue. Select IC from the drop-down list in the Class field (this defines the folder, in which the model is stored) and enter the attributes, which can be used to find the component more easily with the Database Search System. Optionally, you can define additional company-specific properties/attributes. In order to be able to do this, they must have been beforehand in Format -> At tr ibdefined ut e Names.... Click Next once again.

The Structure dialogue is used to define the component’s structure, including any symbols and model that will be used to represent the component in the circuit diagram/layout. If an existing component had been selected as the base for creating a new model and on the first page of the wizard, the Identification dialogue, the option Use attribut es and structure of the following component was selected, then all of the options on the Structure dialogue are active. This means that the user can decide whether and how the structure and the attributes of the selected component will be used: •
•
If you want to Use the current structure , the component can be saved directly to the database without any additional steps. If any modifications are made to the srcinal, remember they will affect all components using this structure, including this one, so be careful! If Make new cop y is selected, the structure can be modified at anytime, without affecting the other components.
If the option Use attribut es and struc ture of the follow ing component
was not selected, as in this
example, then Complete ly new struc ture is the only option currently active. Select this option and press Next once again.
The Complete dialogue is the last step in this process, where the user must decide whether to Save the new component directly to the database or whether it still has to be modified. In the practice example, a Completely new structure was selected, so we must now Edit the component graphically to add the required symbols. Select the option Edit component graphically and close the Component Wizard by selecting Finish .

Editing t he Compone nt Structu re If the option Edit component graphically is selected in the Component Wizard Complete Dialogue, a new component sheet will be opened. It is either empty, in the case of a completely new structure, or contains the symbols/model and with it the structure of an existing component, which will be used as the basis for the new component. The component can now be edited. To define the component in the example, the desired model and all circuit diagram symbols have to be placed on the empty component worksheet and then the schema pins have to be assigned to the corresponding model pins (or vice versa). Select the previously created NAND_FS-symbol from the Database Window (Logic folder in the Symbol tab) and place it 4-times, one under the other, and alongside them to their right, the new SO14-model (IC folder in the Model tab).
E³.logic can distribute information on different levels which can be switched on and off in the drawing. This makes it possible, for example, to quickly switch the visibility of different languages. Entire information types (e.g. empty text) can also be switched on or off. When editing a component, some of the existing information may not be necessary so merely switch it off using the level controls. Start the command View -> Levels... or press the L key. The Levels dialogue appears, in which all or specific levels can be switched on, or off. With the command Read Configuration , you can access predefined on/off level configurations. Select the file componenteditor.vis from the . \ dat a directory and close the menu. You will see that you have a better overview of the component’s affiliated symbols.

Pin Assignment Prior to assigning the schema pins to the corresponding model pins, the first requirement is to define the symbol and model pin names (or vice versa). Right-click anywhere on the sheet and select the Pin Assignment command in the context menu. The command can also be accessed with Edit -> Pin/Core Assignment > Pins... .
To define the symbol pin names, select the Symbol view option in the Pin Assignment dialogue: Only symbol pins will be displayed here; all Unassigned Pins will be identified as such. Select on or several symbols in the dialogue's tree view and enter their pin Names individually. You can also enter the names in the format 1..3 and the names will be added to the pins in sequential order. Assign the symbol pins with indices 15 - 20 to pin names 1 - 6, the indices 21 - 23 to pin names 10 - 8 and the indices 24 - 26 to pin names 13 - 11. Once you have assigned all of the pin names, compare your definitions with the figure at the end of this chapter.

For defining the model’s pin names, select the Model view in the Pin Assignment dialogue. Highlight the component IC1 and enter the values 114 for the Names. Note: Pin names can be entered individually, but it is quicker to enter 1..14 for pin 1 and the pin names will be entered sequentially. Define the power supplies by entering, or selecting from the drop-down list, the value 2:GND in the Signal Equiv. column for Pin 7 and the value 1:VCC for Pin 14 . Clicking OK closes the Pin Assignment dialogue.
To define the schema pins to the corresponding model pins select Edit -> Pin/Core As si gn ment -> Schema/Model or click on the Pin Assignment Symbol/Model button. The schematic symbol pin can then be assigned to its model pin by simply clicking on them. However, these options are available, when the command is active, by right-clicking to display the context menu. With the pin names already assigned in the Pin As si gn ment dialogue, simply select the option Schema/Model Pin Assignment by Pin Name .

To display the logic lines (subsidiary lines) between the assigned schema/model pins, use the command Tools -> Setti ngs... -> Data base Edito r -> Displ ay -> Subsidiary Lines - Between assigned schema and model pins . Alternatively click on the Assignment Subsidiary
Schematic/Model Pin Lines button.
If the lines are not displayed, click on any symbol and the lines will be displayed.
The new component has now been completely described and the only thing remaining to do is to store it in the database, where it can be accessed by all other users. To save the component database, right-click on the the File sheet and select the Save to Database command on to thethe displayed context menuanywhere or by using command menu.
To stop working with the Database Editor, select the command Tools -> Stop Database Editor .
So, now you have experienced how easy it is to define symbols, models and components in the database using the E³.logic Database Editor. With the Component Wizard, it is possible to define additional elements in the database, error-free, so that they can be used immediately in the project.
