Creating all pin symbol containing inherited power\ground connections

saikatc

Hi,

I am working on Virtuoso, version IC6.1.7-64b.500.4. I am using inherited connections in the schematic. AFter parasitic extraction, I observe that the inherited connections are missing in the netlist. I know that it is not recommended to use inherited netlist. Still, is it possible to have a work around so that with the inherited connections we can have a symbol with all the power\ground pins?

thanks in advance.

    Saikat,

    I don't know what PLaSMa is (never heard of it). However, StarRC is a Synopsys tool, so the problem may be how StarRC is generating its extracted views - you would need to contact Synopsys about that, or ask on one of their forums. If it's not in the extracted netlist, it's probably not in the extracted view either - so most likely the issue is related to how the extracted view is generated.

    Regards,

    Andrew.
