P-Cell parameter callback error with layout

yuushabio
yuushabio 10 months ago

I'm using the CCSinvokeCdfCallbacks.il script to update the CDF parameters of P-Cells in my layout. I have access to two different process technologies and the script works fine with one but I get an *Error* eval: unbound variable - schObjPropForm when I try it on the other process. My cadence version is IC618. Any help will be much appreciated. Kind regards.

    Which PDK is it that you're using which is failing (and which device if you know)? I believe this will be happening because the callbacks in that PDK are assuming that the schematic edit properties form has been initialised, which is a bit of an assumption... callbacks should not do this.

    There may be something we could do to workaround this - but would need to know the info above. Failing that, please contact customer support - submit a support case after logging in - (you might need to do that anyway since I suspect a private function may be necessary to workaround this) - please have the application engineer who picks up the case contact me (I wrote CCSinvokeCdfCallbacks).

    It's failing for the TSMC N28 PDK, it works fine TSMC N65 though. I'll submit a support case as recommended. If you're able to find a workaround in the meantime that'll be great too. Thanks for your help. Kind regards.
