It can be done manually or automatically. Automatic clock gating can be peformed for load-enabled registers. Typically, RTL synthesizer maps load-enabled registers to flip-flops and multiplexors (or to load-enabled flip-flops if the standard cell library has them).

WebClock gating options for set_clock_gating_style: 1) Maximum fanout - By default, the fanout is unlimited. This value is the max fanout of each clock gating element. 2) Minimum bitwidth - This is the min bitwidth of register banks that will be gated. Default is 3. Clock gating options for insert_clock_gating: 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. When not b…
