Find your way around the airport, whether you're looking for car parks, … In computer architecture, clock gating is a popular power management technique used in many synchronous circuits for reducing dynamic power dissipation, by removing the clock signal when the circuit is not in use or ignores clock signal. Clock gating saves power by pruning the clock tree, at the cost of adding more logic to a circuit. Pruning the clock disables portions of the circuitry so that the flip-flops in them do not have to switch states. Switching states consumes power.

"WebDec 8, 2024 · It will help solve any hold violations. 3. Increase the clock-q delay of launch flip-flop. Similar to the previous fix, by choosing a flop that has more clock-q delay, delay can be induced in data path logic. It will ease timing and help solve hold time violations. 4. Use a slower cell for launch flip-flop. " - Dft clock gate
