, but it's reporting the schematic FET to have two widths (circuit 2) one of W=12
and another (same device) W=96
, the sum of which is the expected 108
. The netlists being compared look sensible so I'm not sure whats happening.
It's also worth mentioning that the problem doesn't arise when I run LVS on the layout of the block alone. Only when I run LVS on the wrapper containing only this block, vs. the wrapper schematic also containing only this block.
Any ideas anyone? Netlists attached in case anyone can take a quick look. I know you're all also in a mad rush. Good luck and thanks!
Netlists match uniquely.
