WebIf the setup time for the flip flops is 1.5 ns and the maximum clock skew is .5 ns, what is the smallest clock period for which the circuit is guaranteed to work correctly? 2. For the state machine shown below, assume that the flip flop setup time is 2 ns, the hold time is 0.5 ns and the flip flop propagation delay is between 1 and 3 ns. WebIf the flip-flop is being analyzed strictly on its own with regard to the CLK and the D inputs then the minimum clock period approaches the sum of the t setup and the t hold times. The propagation delay only comes into play if the outputs of the flip-flop determine the next state of the D input.
