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 such a specific input ordering matters in Worst case RISE delay or not. In all possible transitions, it seems I end up with the same Elmore delay RC path. WebInterconnect parasitics depends on the process. SPEF supports the specification of all the cases like best-case, typical, and worst-case values. These triplets (best, typical, and worst) are allowed for R, L, and C values, ports slows, and loads. The units of the parasitics R, C, and inductance L are specified at the beginning of the SPEF file.
