BSIM4 import into AWR

Hello,

I am trying to import a cadence BSIM 4.4 model file (.scs) into AWR from a foundry PDK (built for Spectre RF). The parsing and symbol creation go through fine but it comes up with a load of "Variable not valid" errors. Some examples below:

"toxe_n33 - Equation Error: Variable 'dthkox@' is not valid"

Same for: mc_gl_f@, cnr_toxd@, dthkox@, cnr_n33@, etc...

I expect the Cadence environment takes care of these somehow. Wondered if anyone knows a solution for this or has come across this before.

AWR version I am using is:13.02r build 8379 Rev1 (104876) (64-bit)

Many Thanks,
Chris.
