Run Skill Scripts and Update Schematics from Unix Command Line

hi,

Yes, IPC commands are for running linux commands from an icfb/virtuoso session.

To run skill code in batch mode, you could do:

          icfb -nograph  -replay MYSKILL.il -log MYBATCH.log

to run skill in batch mode.

good luck!

Hi,

In addition to what Nani said you may also be able to run the executable "dbAccess" which is a non-graphical executable which contains core SKILL functions plus functions that could be run inside of a Pcell, these include db* prefix functions, dd* functions, rod* functions and tech* functions.  No graphical capabilities exist at all within dbAccess, so functions like hi* or ge* will not work, and the application SKILL API's are not present either, so no sch* or le*.  Having said this, it is a useful tool for performing core SKILL functionality or testing PCells to ensure that they would run in other environments (e.g. for Stream Out use). This executable is not officially documented yet, but this is coming soon.

Best regards,

Lawrence.

Oh, I forgot to mention, ipc* functions are implemented dbAccess.

Lawrence.

 You're right. This post has nothing to do with what you're trying to do (and you've asked that elsewhere in the forum).

Hello I try to run the below given command

virtuoso -nograph -replay ../RO/INV42/SKILL/INV42.il -log  MYBATCH.log

However the error is the following:

The skill file must generate a layout pcell. I cannot generate it when i execute the -nograph command from command line but i can generate the layout, if i load the skill file in CIW window.

Please guide me with the debugging pointers

Ahmad.

Hi Ahmad,

Those were Warnings not Errors, and anyway, I see the following message at the end of the section you posted:

Successfully connected to a non-graphical X Window Display server.

I suspect that the PCell issue is due to something else - where is the error relating to being unable to generate the PCell?  Have you run the SKILL Lint tool on your code to scan for possible issues? (Access it from Tools -> SKILL Development environment when using IC61x/ICADV12x ).

If the -nograph really is the source of the issue, did you try taking a look at the log files?  The documentation notes the following:

Note: cdsXvnc can leave locked files in /tmp if it exits abnormally (for example, it is killed or crashes). In such cases you may be displayed warning messages like:

*WARNING* Could not open display sfsol804:80. If no X server is running for
*WARNING* this display, please remove the file /tmp/.X11-unix/X80.

----

Also you could try -nographN where N is 0-9 to see if that helps.  Post back with your efforts and results...

Good luck!

Regards,

Lawrence.

Hello Lawrence,

  Thank you very much for your prompt response. The error is form myside in environment setup. 

  virtuoso -nograph1 -replay ../RO/INV42/SKILL/INV42.il -log MYBATCH.log is working perfectly.

I also need a help:

Is there any command which can generate a gds file from a script file.....I need to use this command in a script .

Thanks & Regards

Ahmad

The UNIX command "strmout" can be used. Try invoking it without any arguments to see the help for it.

Andrew.
