Homework Answers
Ans-3
Option c is correct answer.
Because change in A will reflect in B only after a clock cycle . Similarly change in B will reflect at S only after a clock cycle. But to ensure that setup violation is not met data must reach little early before the next clock cycle.
This is best described in last waveform because change in B is reflected at next clock cycle after change in A but little early to ensure system does not meet setup violation.
Similarly change in S is reflected a clock cycle after B but little early to ensure system does not meet setup violation.
Ans -4
Option a is correct.
Because when system sees setup or hold violation the circuit will miss change in its input, that is circuits output will not change to reflect change in A.
So to not miss correct output we sould take care that there are not any setup or hold violations in circuit.
