Question

16. For a hypothetical state machine you have just designed, the flip-flops have a propagation

delay of 4ns and a setup time of 1ns. The output decoder has a propagation delay of 2ns and

the next state decoder has a propagation delay of 2ns. Calculate the maximum clock

frequency for this state machine and describe what will likely happen if the machine is

clocked at a higher frequency than this.
