Dear Marq and Rad,
dcmismatch simulation parameters have nothing to do with the mismatch data meant for MC statistical analysis. These are 2 things different altogether. There is a thread in the Cadence's sourcelink where the difference between DCmismatch and MC statistical mismatch is detailed. Can't remember the SR number off the to of my head. A little search would spot it out.
The dcmismatch data is often available within the TYP corners. For BSIM3V3 MOSFETS, Spectre does support the following parameters for dcmismatch : (spectre -h bsim3v3)
; DC-mismatch dependent parameters: 279 mvtwl=0.0 v*m Threshold mismatch area dependence. 280 mvtwl2=0.0 v*m^1.5 Threshold mismatch area square dependence. 281 mvt0=0.0 V Threshold mismatch intercept. 282 mbewl=0.0 m Beta mismatch area dependence. 283 mbe0=0.0 Beta mismatch intercept. 284 mismatchmod=0 select Mismatch mode. 285 mismatchdist=0 m Mismatch Distance. ;
One can then grep one of the above parameters in the model file to check whether the data is there or not.
There are ways of extracting these parameters otherwise, a bit tricky but still possible in some cases ...
Cheers ;) Riad.
