I don't think I can answer these questions because it completely depends on how the sections in the model files have been written. It might be that they have statistical mismatch parameters in all sections, and then process+mismatch statistical parameters in the MC section - I have no idea (this is just a wild guess). If it was that, then I'd expect that if the test models were set to: MOS_model.process.mc.scs --> SS and CAP_model.process.mc.scs --> MAX and the corner was set to: MOS_model.process.mc.scs --> MC and CAP_model.process.mc.scs --> MC Then I'd expect that a mismatch-only simulation with both these enabled would do mismatch around SS/MAX for the "nominal" and mismatch around typical (assuming that the "MC" section is centred around the typical process corner). So they may not be the same. However, this is all guesswork - I have no idea of how your models are set up (since I don't know what technology you're using - and even then I'm not sure I could talk about it here). Presumably the foundry documented what the model sections do and how they should be used somewhere... if not, ask them! For your second concern, I can't answer as well because I don't know where these MC model sections are centred about (but I'd guess they are centred around the typical process values). So in your terminology that would be MOS-TT and CAP-TYP (not sure why it would be CAP-MIN). However, this too is guesswork. Regards, Andrew.![]()
