Recognize the type of circuit

Question

Explain why do we have to recognize the type of circuit? Does it actually matter?

Answer 1

It is significant to recognize the kind of circuit as our timing computation approach varies accordingly. Combinational circuits timing analysis mainly deals primarily with the propagation delay issues. The sequential circuits encompass additional specific timing features which should be satisfied in order to prevent the meta-stability, comprising setup time, hold time and minimum clock period. The designers of sequential devices should specify such significant timing features in order to permit the device to be used devoid of error.
