Starting Virtuoso Studio

To start Virtuoso Studio from a UNIX prompt:

1. Change to the working directory from where you want to start the software: cd <your_working_directory>
2. Confirm if the Virtuoso Studio executable is set properly: which virtuoso
3. Define the design library and reference libraries (cds.lib).
4. Type the command to start the Virtuoso Studio software: Virtuoso &

Examples of starting a Cadence workbench follow:

• To start Virtuoso Studio as a background process, type the following command:
  

  virtuoso &

  The splash screen is displayed before the CIW opens.
  
  
  To disable the displaying of the splash screen use the shell environment CDS_NOSPLASH the command line option -nosplash.
  The CIW appears.
  
  
• To start Virtuoso Studio as a background process, with outputs being sent to a log file, type the following command in CIW:
  

  virtuoso -log 1.log &

  In this case, output sent to the terminal also gets written to the log file, which can be accessed later, even if Virtuoso Studio exits unexpectedly.
  Alternatively, you can use the following options in Linux:
  • Before closing the terminal, press Ctrl+Z to interrupt the process and use the bg command to put the process in the background.
  • Launch Virtuoso Studio using the screen command as follows:
    /usr/bin/screen virtuoso -log myLog
    In this case, even when the terminal running screen is closed, Virtuoso Studio continues to run.
• To start Cadence software in non-graphics mode, type the following command:
  

  virtuoso -nograph

The CIW does not appear. The Design Environment prompt (>) appears.

Do not use an ampersand (&) after the command in nongraphics mode because you want to interact with the software rather than run the software in the background.

• To execute a SKILL file automatically on starting, type the following command:
  

  virtuoso -nograph -replay fileName

where fileName is the name of the SKILL file you want to execute.
