Is there a way to include matching into corner analysis (in spectre / MMSIM60)?
In my case I have two (!!!) differential pairs which should match - but during corner anlysis for the "wp-case" the gm of the two pairs change in different "directions" -t his means the gm of the pmos in one pair rises and in the other pair drops. But as I have used a mathcing layout for all the 4 transistors this shouldn't couldn't be the case obviously ...
so what to do - (no corner analysis - only monte carlo (???)
