WebRC_worst_fastProcess_LowTemp_HighVoltage: This scenario is worst case check for power analysis. RC worst parasitic corner results in high power dissipation in interconnects, whereas fast process, low temperature and high voltage result in fast transition of the signal. Again, this corner can be used to analyze power at any functional mode. WebSep 28, 2015 · Add to that the fact that increasing delay is bad for setup timing but good for hold timing, and vice-versa for decreasing delay. So all you can say is that by picking different R and C combinations you will get a different delay picture for your circuit. Not necessarily better or worst, just different.
