Modifying BSIM-IMG model and using it in Cadence

$

Hi,

I'm trying to modify BSIM-IMG model from Berkley http://bsim.berkeley.edu/models/bsimimg/ for my application (I'm trying to modify the temperature related formulas for Cryo application). I have made my modifications, but I have no idea how to properly use that model in cadence, I tired using the veriloga model that the BSIM-IMG comes with, but it's not working, not even the original (unmodified version of it). Is there a way to directly modify the pdk files formulas? or is there a simple way to have cadence point to the model and not create a whole veriloga model? because in the veriloga model, the parameters don't even designate pmos vs nmos. Please advise on how to use the BSIM-IMG model with cadence. Thanks!

-Daniel
