Dft clock gating

WebIn 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 … WebFor an active high latch, the gating signal should toggle on the falling edge of the clock.
