Dff timing
Web• Advantages in timing discipline – Since edge-triggered flip-flop equivalent to transparent latch, there is essentially 0 setup time – Hold time is equivalent to glitch width – Clock-to-Q delay is only two gate delays • Reduced clock load and few devices, low area for lower power • Can use glitch circuit (one-shot) to generate Web• Latch timing issue – transparent when C = 1 – state should change only once every new clock cycle • Master-slave flip flop – break feedthrough 7 Combina- tional Logic D Latch ... (DFF) • Why edge trigger? • D replace S and R input 9 C S R Q Q C Q Q C D D Q Q C D Y Q Slave out Master out Master active Slave active no 1’ catching

WebFrom: CK Hu To: , , , , , , Cc: , , WebApr 19, 2012 · Hold time is defined as the minimum amount of time after the clock’s active edge during which data must be stable. Violation in this case may cause incorrect data to be latched, which is known as a hold violation. Note that setup and hold time is measured …

WebIt is the property of latch, a path ending at a latch can borrow time from the next path in the pipeline such that the overall time of two paths remains the same. STA applies a concept of time borrowing for latch based designs. Whatever data launched from Flip Flop1 at ons it should be reached to Flip Flop2 at next active edge i.e. 10ns (ideal ...
