Consider a FF1-Comb-FF2 circuit, both flops clocked by same clock clk1.
If clock frequency of clk1 is 16 ns, Comb delay is 0 ns, FF set up time is 0.2 ns and Clock uncertainity is 0.5 ns,
1. What will be max operating freq of this system. ?
2. Will clock unceratainity be used in max freq calculation ?
Theriotically, the maximal frequency is (1/0.7)GHz
clock uncertainly always be used to estimate the clock skew or jitter or reserved margin
usually, circuit highest frequency is determined by the critical path...
