Modeling and simulation of FinFET in cadence

RAJ JOHRI

Hello. I m MTech student. I want to simulate FinFET based digital circuits. But I don't have a FinFET model in cadence. Please help me by providing an equivalent model of FinFET or any other way to simulate FinFET.

Thank You.

  • I downloaded the model from this page:

    http://www-device.eecs.berkeley.edu/bsim/?page=BSIMCMG_LR

    I am a student doing my project using college computers. And everytime I use Cadence, I type 'ic6 gpdk18' in the terminal. I don't know if my Cadence version is too old or not. I cannot find the bsimcmg model in the library (analogLib, basic and gpdk180). The only one I found is bsim4 in analogLib but I need a model to simulate FinFETs. And it seems that I cannot update it because it is a college computer. So I decide to create this model by myself.

    The model I downloaded gives a symbol with 4 pins (s, d, g, e). It seems that the parameter settings are done in the .sp test file (such as L and NFIN)  in the file 'Benchmark_test'. So I don't know how to change them in Cadence.

    Sure it's OK and you can take a look at anytime. Thank you very much for the help.
