What are the main reasons for setup or hold time violations?
Main reasons for setup or hold time violations
- Design issues.
- High clock slope.
- Capacitance coupling.
- Very fast transition from the output of flip-flop A to the input of the flip-flop.
- Sharp clock skew rate causes a first clock edge delay before the second clock edge. The alignment of the two clock edges is not synchronized.
Which factors decide setup time and hold time?
The set-up time and hold time are calculated by the input data slope, clock slope, and output load
