Flip-Flops and Hold Time Violations

Digital circuits necessarily include storage elements to ensure correct operation. The most common are the flip-flops (FFs). Although they are not very difficult to use, their operation must be understood and they must be characterized due to their timing metrics. They are not immune to failures, and one failure that FFs can present is the hold time violation, if they are not carefully designed. This chapter discusses FF operation and metrics, and hold time violations.
