Is there anyway to calculate setup and hold time of a D flip-flop in cadence by using calculator, or any tools in cadence? WebHold Time for Flip Flop: Take a clock of pulse width 10ns i.e. a frequency of 100MHz Consider data transition from 0 → 1 at infinite setup time say 10ns before the active clock edge. Keep on bringing the data closer to the active edge of the clock.
