Does nghspice support FinFETs.
Also, can u suggest any other software that will allow FinFET models.
nghspice would be a nice combination, but finally you have to decide …
The FinFET model parameters from ptm rely on the BSIMCMG model developed at UC Berkeley (http://www-device.eecs.berkeley.edu/bsim/?page=BSIMCMG). ngspice does not support this model. You will have to check for a simulator offering the BSIMCMG model.
