What Is a Timing Violation

Timing violations occur when the execution time requested by sections of code is shorter than execution time the bitfile achieves after compiling.

How do I fix my time violation?

1. Use larger/stronger cells to drive paths with high capacitance, which can reduce the time needed to transition on sluggish net.
2. Adjust the skew of the clock to the start or endpoint of the path which is violating.

What happens when setup time is violated?

Setup time is defined as the minimum amount of time before the clock’s active edge that the data must be stable for it to be latched correctly. … Violation in this case may cause incorrect data to be latched, which is known as a hold violation.
