I am seeing a significant discrepancy between the Spectre and SpectreVerilog simulators. The circuit in question is a bootstrapping circuit - and what I'd like to do is track down exactly which models each simulator is using.
I'm familiar with the switch/stop viewlists, but I think the issue might be in the model structure. Instead of an .scs file for each device in the kit, the model files are setup as process corners and have different sections (fast, typ, slow, etc). Then while simulating I have to go to 'setup corners' or 'corners' from the Analog Environment window and select typical for actives, resistance, capacitance, etc. So If I select fast for poly, the simulator apparently generates the correct model for each MOS device.
I have also setup AMS and the results here match with SpectreVerilog.
So, if I can get some help tracking down exactly what model is being used for MOS devices in each case I'd be most appreciative!
Thanks!
