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.
