WebClock skew Goal: Clock all flip-flops at the same time Difficult to achieve in high-speed systems Clock delays (wire, buffers) are comparable to logic delays Problem is called clock skew Original state: IN = 0, Q0 = 1, Q1 = 1 Next state: Q0 = 0, Q1 = 0 (should be Q1 = 1) CLK0 clocks first f/f CLK1 clocks second f/f CLK1 should align with Webthe Hogge PD in the presence of finite delays in the flipflops. Owing to the CK-to-Q delay, ∆T, of FF 1, B changes ∆T seconds after the clock rises, yielding a pulse at the Y output that is ∆T s wider than the actual phase difference between D in and CK. On the other hand, the CK-to-Q delay of FF 2 simply shifts the pulses at A by ∆T, medserviceswebpap.com
