I would like to modify a model parameter of a MOSFET while instantiating it e.g. threshold voltage parameter VTH0 of BSIM3V3 mosfet parameters:
M1 1 2 3 4 w=10u l=2u VTH0=0.5
However HSPICE does not allow modification of model parameters this way. Some other versions of Spice do allow this. Is there a way out?
The reason I wish to modify VTH0 is to run a Monte-Carlo sim for threshold voltage mismatches.
