Please log in for more thread options Try change references on original SUBCKT, from N1 and P1, to N1_XN and P1_XN. (one thing I despise on SS is this of adding _XN on models. I think SS could just assume that model without _?? is plain model without worst case models) []s -- Chaos Master®, posting from Canoas, Brazil - 29.55° S / 51.11° W (GMT -2 (BRST) / GMT -3 (BRT)) "Two of the most famous products of Berkeley are LSD and Unix.

Pity too, 'cause SS is the only CAD that comes close to digesting this file. SIMetrix doesn't find the subckts, just the models and the file was written *for* SIMetrix by Hans Camenzind. Recently! Assuming this gets figgered out, that Cap in the subcircuit is across part of a substrate subckt, i.e., a 1 ohm resistor. It causes a singular matrix. 1 pf || 1 ohm. increasing GMINSTEPS and SRCSTEPS doesn't help either. -- Best Regards, Mike | |||||||||||||||||||||||||||||||||||||

There are other issues, which make this approach a sensible way to do things. Methods are always a trade off.

I understand this, but why don't you consider adding option to disable this? Some users aren't going to use WC/MC, after all.
