include a model files for nmos and pmos into virtuoso

 HI all,

how can I include a model files for nmos and pmos into virtuoso like the one which is attached. I want to use this model file as it has equal threshold voltage for pmos and nmos. It is needed only for simulation results.

Regards

    In the old spectreS and cdsSpice interfaces you needed to have model files (in cdsSpice format) with the ".m" suffix. With spectre, the suffix doesn't matter, except that if the suffix is ".scs" it is assumed to be in spectre language, whereas any other suffix is assumed to be in SPICE language. Your models are in SPICE language, so pick anything other than ".scs". There is the "simulator lang=spice" or "simulator lang=spectre" directive that can be used to override this if needed, but you don't need that here.

    Regards,

    Andrew.
