Spectre model aliasing

CSCNalu

Hi

I have a (I think) really simple question - our spectre models use a name for our transistors but an IP provider used a different name for our MOS that it uses and I was wondering if there's a way to alas the names from the IP provider to map them to our PDK names.

Basically the spectre models we have from the foundry use let's say "nch" for an nmos but the IP provider uses "N" in their spectre netlists.  Since it's a standard cell library it uses the model a few million times and since it's a proper foundry provided spectre model it also references the models a few other bajillion times...basically is there a way to create a short in the spectre definition that will map these models together since they're the same MOS?  I need to do this for both P and N.

Thanks

Chris

    Chris,

    Yes, all you need to do is put this in a .scs file:

    model N nch
    model P pch

    This aliases N to nth, and P to pch.

    Regards,

    Andrew.
