How to use BSIM-CMG models to build and simulate FinFET circuits

Ahmed Taha

Hi All,

I need to simulate FinFET based circuits

I have BSIM-CMG codes and models from www-device.eecs.berkeley.edu/.../

this includes veriloga files.va and files.include and model card.nmos files

I tried several methods to add these in Cadence, but still something missing 

so I am asking about the right way to add such files to enable circuit simualtion. 

 if any one managed to do this before, could help.

Thanks

    I see very little point in using the VerilogA implementation of the model. bsimcmg is built-in to spectre in MMSIM72, MMSIM101, MMSIM111, and MMSIM121 (that's the last four major releases;  MMSIM72 was released in 2009, so it's been there for a while).

    So Cadence has supported this for some time.

    I've not tried using the VerilogA model (for some time), but to be honest, you would be far better off using the optimized production versions. I can't see much point in sticking to a simulator release which is more than 4 years old if you don't have access to it right now? I suspect that you would need a similarly aged version of HSPICE to support this natively too, if you're using HSPICE.

    Kind Regards,

    Andrew.
