bug

There is a bug ... in bsim4.va, lines 12356 and 12357.

These statements effectively disconnect di,d and si,s if BSIM4rdsMod is not set.
Otherwise they seem correct, and they should be made conditional on BSIM4rdsMod.

The discussion is in a different repo [1], and the conclusion there might involve removal of the model. I think it should be fixed instead. Maybe here?
