check the instance symbol change in schematic

lzyc

Andrew (or anybody),

If an instance symbol is modified after the schematic last modification, cadence will give you warning in CIW when you open the schematic. I want to write a skill code to check the schematic for the same purpose?  Initially I thougt cadence only compare the timeStamp of the schematic and the instance symbol. But I found cadence does more than that. They can capture the symbol change even if I rollback to a old sybmol version (with earlier timestamp). Can you tell me how Cadence capture the instance symbol change when you open the schematic?

    Hi Andrew,

    You are right, I was giving the viewName of symbol instead of schematic viewName. I corrected, now i could see 'nil' if symbols in the schematic remain unchanged  and some database ID if symbols are changed.
    Is there a way where i could get a notification whenever symbol is checked in? I need to update port list of behavioral model whenever corresponding symbol gets updated. Can you suggest me how can i proceed.

    Regards,
    Amul

    Hi Amul,

    You should probably contact the provider of your design management software. Given that you may have some complex multi-site DM setup (I have no idea) - but even if it's another user on the same network - there would need to be some trigger in the DM software to send notifications to interested parties when checkins are performed. Potentially that could be written using ddRegTrigger (with the "PostCheckin" event) but that probably depends on whether it's using a GDM integration or not and whether the checkin is performed using the Virtuoso API. Even then you'd have to write the code to send a notification (whatever form that takes).

    So best to speak to your DM provider because there may be some functionality built-in to their solution that already allows a notification.

    Regards,

    Andrew.
