For gate level simulation that has been annotated with an SDF file, when there's a setup/hold violations on a flip-flop the following will happen by default: (1) The FF's output will change to 'X'. (2) a timing violation assertion will be generated.

WebFeb 3, 2024 · Each of the four timing situations is a potential failure for your design. Each of them reflects a way that your design is specified to the user...maximum clock frequency, input setup time, and so forth. You should use STA to verify that all of those requirements are met.

If the Hold Time Violation is associated with an OFFSET IN constraint, the data path is faster than the clock path. Either increase the delay associated with the data path or decrease the delay associated with the clock path. To decrease the clock path delay, verify that the design is using the global clocking resources. You can …
