How to get back to tcl after exiting in OCEAN and/or SKILL?

Reinice

Hi All,

Good Day. 

I 'am running tcl in compiling/creating OCEAN and/or SKILL files. When I exit in OCEAN and/or SKILL I can't get back to tcl to compile the remaining tcl codes. Is there a way to get back to tcl after exiting in OCEAN and/or SKILL?

Thank you very much in advance.

Regards,

Reinice

  • Hi Reinice,

    Are you running "ocean" with "-nograph"? I'm wondering whether maybe you have a popup which is appearing but you can't see it because you're in nograph mode. Maybe if you run without -nograph mode you see it?

    Also try running the same OCEAN script from the command line (rather than from within Tcl) to see what happens. Even try "virtuoso -restore yourScript.ocn" and see what happens.

    Sometimes the popup that appears at the end is because of:

    a) something that needs saving (in which case maybe doing a dbPurge() of the design will fix it)
    b) modifications to the display.drf being done as part of a PDK's libInit.il (using drLoadDrf without nil as the second argument)

    I have seen people solve this by calling exit() twice in the OCEAN script, but that's a bit of a hack - better to try to find the root cause.

    Regards,

    Andrew.
