While running a harmonic balance analysis on my rectifier, I receive warnings such as '
CMI-2426: M3: Cdscd = -28 is negative.
CMI-2426: M1: Pdiblc2 = -31 is negative.
I understand that these are parameters of the MOSFETs specified in the specific PDK, but I have no idea why they keep popping up?
Any clues for the same would be great!
