@User: I forget where the thread was, but you claimed that you could swap + and - pins of an op amp and it would pass LVS. . . Yes, you are right. This basic pin check was in the netgen code, but a routine was added before it that is supposed to just match all pins by name for black box entries. Problem was, it didn't actually check if the cell was a black box or not. That caused netgen to just quietly ignore pin mismatches as long as the names were the same (working on a fix now).
