WebMay 27, 2014 · For the hold time, below 130nm, it is better to check the hold time in best and worst corners. In 65nm we saw hold time issue when we cross, the RC best/worst/typical with the corner worst/best, I means we have multiple corners, like worst-RC worst, worst-rc best, worst-rc typical...., and we check the hold time in all of this mode. WebSpecifically, if the input which has it pfet's source connected to VDD is switched from 0 to 1 , then this will incur the worst case Elmore RC FALL delay. However, I am thinking whether …
