include a model files for nmos and pmos into virtuoso

auto dipper

 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

     Thanks for the confirmation, I tried to do the way as you suggested and the simulation happened but I got the below Notice in the output log file

    Notice from spectre during initial setup

    Pmos: Value of ‘kp’ and ‘u0’ are not consistent

    Nmos: Value of ‘kp’ and ‘u0’ are not consistent

    What is the effect of above on output and how to remove this?

    Another issues is that as I observed the number of parameters in any other model file like ami06.m is 94 but the model file I am using for equal threshold voltage (attached) has only 27 parameters. So where will the issues arise in using such model file with less no. of parameters?

    regards
