Summarize:Simply put, because the flip-flop port to the gate has a delay, if the clock that paragraph delay is significantly larger, the setup may be negative, if the flip-flop port Gata that period of delay is significantly too large, hold may take a negative value. In my opinion, both of them are used to fine tune the same asynchronous problem when the data and clock pass through the filp-flop, so that the data and clock can not be changed so that the flip-flop transmission signal is not passe
