Forcing Virtuoso to update lib references after changes in cds.lib

alexcb

Hi,

I am currently running Virtuoso version ICADV12.3-64b.500.21. 

I noticed that when I "undefine" a library in the cds.lib, the definitions of cells contained within that library still exist in memory. I can test this by checking any open cellviews that have references to undefined cells. The cells are still visible, and will not be replaced by any markers. There also will be no errors complaining that these cells do not exist. This of course is fixed when I restart Virtuoso. However, I currently need a means of signalling which cells have been undefined without having to restart Virtuoso each time I change a line in cds.lib. 

Is there a way of doing this? Ideally I would like to purge all remnants of undefined libraries from memory, or "refresh" all library references.

Forgive me if I haven't been using the terminology correctly, I'm still new to Virtuoso and Cadence SKILL. I would appreciate it if you could correct me on any mistakes that I have made!

Thanks,

Alex

    Hi Alex,

    If you do this (change the cds.lib) to undefine a library, and then do File->Refresh (or use ddUpdateLibList() in SKILL), you'll get a popup telling you everything that is open - it won't honour the change in the cds.lib until you close the data that is still open (via the File->Close Data form).

    So I'm not sure you need any SKILL to do this...

    Regards,

    andrew.
