Web6 Oct 2016 · Note that the maximum rate a shift register can go is 1 t s u ( m i n) + t p r o p ( m a x) as the D input must be stable for at least the setup time after the previous Q output has become stable. Provided the propagation delay is greater than the hold time, it can be ignored for the maximum clock rate. Webhold time: 时钟沿到来之后输入信号D必须保持稳定的最小时间. clk-to-q time: 输入D满足setup/hold time要求，从时钟沿到来时刻到输出端Q变化至稳定的时间. 那么当输入信号D无法满足setup time 或者hold time的要求，我们称之为产生了setup time / hold time violation, Flop Q的输出这个 ...

WebFor setup- or hold-time optimization analysis, a normal bisection method varies the input timing to find the point just before failure. At this point, delaying the input more results in failure, and the output does not transition. In pushout analysis, instead of finding the last point just before failure, the first successful output transition ...
