Supported User Interfaces Genus supports the following user interfaces: ■

Unified User Interface. Genus, Innovus and Tempus offer a fully unified Tcl scripting language and GUI environment. This unified user interface (also referred to as common UI) streamlines flow development and improves productivity of multi-tool users. When you start Genus, you will by default start with the common UI. You will see the following prompt: genus@root:>

■

Legacy User Interface. Genus can also operate in legacy mode which supports RTL Compiler commands/attributes and scripting. To start Genus with legacy UI, you can ❑

Start the tool with legacy UI as follows: %genus -legacy_ui -files script .... legacy_genus:/>

❑

Switch to legacy UI if you started the tool with the default common UI. %genus genus@root:> set_db common_ui false legacy_genus:/>

Important This document provides information specific to the common user interface.


13



Messages ■

You can get detailed information for each message issued in your current Genus run using the following command. genus@root:> report_messages

The report also includes a summary of how many times each message was issued ■

You can also get specific information about a message. For example, to get more information about the TUI-613 message, you can type the following command in both user interfaces: pr om pt > vls -a

TUI-613 message:TUI/TUI-613 (message) Attributes: base_name = TUI-613 count = 0 escaped_name = TUI/TUI-613 help = The user_speed_grade is only applicable to datapath subdesigns. id = 613 name = TUI/TUI-613 obj_type = message print_count = 0 priority = 1 screen_print_count = 0 severity = Warning type = The attribute is not applicable to the object.

You can also use the help command: genus@root:> Message: name: severity: type: help: subdesigns.

help TUI-613

TUI/TUI-613 Warning The attribute is not applicable to the object. The user_speed_grade is only applicable to datapath

If you do not get the details that you need or do not understand a message, either contact Cadence Customer Support to file a CCR or email the message ID you would like improved to [email protected].


14



Man Pages In addition to the Command and Attribute References, you can also access information about the commands and attributes using the man pages in Genus. Man pages contain the same content as the Command and Attribute References. To use the man pages from the UNIX shell: 1. Set your environment to view the correct directory: man_common setenv MANPATH $CDN_SYNTH_ROOT/share/synth/

2. Enter the name of the command or attribute that you want either in Genus or within the UNIX shell. For example: ❑

man check_dft_rules

❑

man cell_leakage_power

You can also use the more command, which behaves like its UNIX counterpart. If the output of a manpage is too small to be displayed completely on the screen, use the more command to break up the output. Use the spacebar to page forward, like the UNIX more command. genus@root:> more man syn_map


15



Command-Line Help You can get quick syntax help for commands and attributes at the Genus command-line prompt. There are also enhanced search capabilities so you can more easily search for the command or attribute that you need. Note: The command syntax representation in this document does not necessarily match the information that you get when you type help command_name . In many cases, the order of the arguments is different. Furthermore, the syntax in this document includes all of the dependencies, where the help information does this only to a certain degree. If you have any suggestions for improving the command-line help, please e-mail them to [email protected]

Getting the Syntax for a Command Type the help command followed by the command name. For example: genus@root:> help path_group

This returns the syntax for the path_group command.

Getting Attribute Help Type the following: genus@root:> help attribute_name

For example: genus@root:> help max_transition

This returns the help for the max_transition attribute and shows on which object types the attribute can be specified.


16



Searching For Commands When You Are Unsure of the Name You can use help to find a command if you only know par t of its name, even as little as one letter. ■

You can type a single letter and press Tab to get a list of all commands that start with that letter. For example: genus@root:> a

This returns the following commands: ❑

■

add_assign_buffer_options add_clock_gates_test_connection add_tieoffs after all_clocks all_fanin all_inputs all_outputs analyze_library_corners analyze_testability append_to_collection apply array attribute_exists auto_import auto_load_index

add_clock_gates_obs add_opcg_hold_mux add_to_collection alias all_connected all_fanout all_instances all_registers analyze_scan_compressibility append applet apropos assemble_design auto_execok auto_load auto_qualify

You can type a sequence of letters and press Tab to get a list of all commands that start with those letters. For example: genus@root:> path_

This returns the following commands: path_group


17



Documentation Conventions To aid the readers understanding a consistent formatting style has been used throughout this manual. ■

UNIX commands are shown following the unix> string.

Genus GUI Guide Getting Started with GUI

Overview of the Genus GUI The Genus GUI is designed for synthesis users who want to use physical information to drive synthesis but are not interested in creating the physical details. It serves as an analysis tool to help you identify design problems, such as timing and power. Features of the Genus GUI: ■

Viewer Windows are dockable. You can move them around in your display area.

■

Automatically loads preferences that were saved in the ~/.cadence/genus/gui.tcl file.

■

Automatically updates itself after using major commands.

■

Provides a status bar associated with every viewer, showing transient messages and persistent messages as shown Figure 1-1.

■

Provides Design, HDL, Schematic, and Layout Viewer windows. See Chapter 2, “Using the Viewer Windows,” for detailed information.

■

Provides interactive GUI commands so that you can write your own scripts to interact with the GUI and to add features that are not part of the normal installation. See Chapter 3, “GUI Text,” for more information.

■

Selects and cross-probes objects under the cursor to the Design, HDL, Schematic and Layout Viewers whenever applicable.

■

GUI reports can be sorted and filtered on various parameters in that particular report.

See Chapter 3, “Using the Menu Bar. Bar.” The menu bar contains various commands that have command-line c ommand-line equivalents too. For example, you can hide the GUI by typing the gui_hide command, or by using the File menu menu or by pressing key sequences. Search option is also available on the menu bar which helps to search across the complete “Cadence Online Help”. But to use this search, you should be connected to the internet. If you have problems finding information, see Customer Customer Support Support on page 12 12 for for detailed information. Viewers All other windows, except the menu bar, are referred as viewers in Genus. All viewers are detachable. These can be moved around freely within your display area. This is a useful feature when having an extended monitor setup.


23


Genus GUI Guide Getting Started with GUI The viewers give a peak into the design from different viewpoints. For For example, the Schematic Viewer lets you see the design from a designer’s perspective but the Layout Layout Viewer gives an idea about the die and the placement of different modules inside the die-area. In Genus, there are five different viewers to fulfill different requirements namely Design Browser, HDL Viewer, Schematic Viewer, Layout Layout Viewer and Object Attributes. Every viewer has its own submenu on the top of the Viewer Window and a status bar at the bottom. For detailed information on the viewers, see Chapter 2, “Using the Viewer Viewer Windows. Windows.””

Every Toolbar is explained in detail in Chapter 2, “Using the Viewer Windows.” Status Bar The Status Bar is also associated with the viewers. Every viewer has its own status bar. For details, refer to Chapter 2, “Using the Viewer Windows.”. Context-Sensitive Menus There are context-sensitive pop-up menus that are associated with every viewer. These are different for different viewers and also for different components in a single viewer. To view a context-sensitive menu (also called as the shortcut menu), click the right mouse button on the selected object. Following is a list of tasks that can be carried out through the shortcut menus.

Exiting the Genus GUI There are two ways to exit the GUI: ■

From the menu bar, choose Fil e – > Ex it Tool and click Ok . The Exit Tool dialog box appears:

The Hide GUI command is equivalent to the gui_hide command and it hides the GUI but leaves the command line interface open. Type the gui_show command to re-display the GUI. Exit option is for exiting the tool. Cancel option is given in case you have accidently hit this option.


26



■

Pressing the cross-button on the top-right corner of the GUI. It will again give you the option to “Hide GUI ”, “Exit ” or “Cancel ”.
