You use HSPICE?

Added after 1 minutes:

Google for "CMOS +PVT",you will find the answer.
 

You need simulate various combination for corners and different VDD and different temperature. At the least, the highest and lowest VDD and -40degree and 100degree are needed.
 

you can use the .param to change the source voltage.
