Running Cadence Virtuoso in command line without GUI

Naveen16 over 6 years ago

Hi, I have a question on how to perform SKILL functions in command line mode.

What I want to do is to

(1) start cadence with no GUI.

(2) perform a series of SKILL function (defined in a do file) such as adding tech file to a library, adding layers.

(3) quit cadence

Heard that virtuoso -nograph option would work but it looks like I need to setup some unix environment variables to make that command work. Not sure what environment variable should I be adding in .kschrc files. Can anyone help?

Thanks.

I don't see why you should need to set up any UNIX environment variables to run "virtuoso -nograph". Essentially what you are trying to do could be done with "virtuoso -nograph -restore code.il". Potentially you could use the lighter "dbAccess" (e.g. dbAccess -load code.il).

Regards,

Andrew.

The only way I can get this is if I put "-nograph" on a separate line. Maybe you have a wrapper script around virtuoso so what you're running is not actually the virtuoso from the Cadence installation?

Perhaps you should check where virtuoso using "which virtuoso" and see whether there's a wrapper in the way.
