WebIn this way, the logic from the FF to the clock gator is just a wire, and meeting timing become easy. It is tricky to decide what should be the latency for the pair of FFs (in front of the clock gator). Ideally, they should have shorter latency. However, if you want to include them in the scan chain, then it is better to balance them.
