WebBy default, the clock gating check is not inferred for complex combinational cells such as MUX, AND-OR, XOR because the clock is never in the controlling state. However, you can force clock gating on MUX by specifying explicitly either -high or-low option with set_clock_gating_check command. Webof the RTL clock gating feature in Synopsys Power Compiler.

Whose power reduction is better. Clock gating or Data enable?

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… WebHere, the scenario is that, the antecedent is true and the consequent is checked between 1 & 100 clock cycles. After the antecedent, the clock is stopped due to clock gating for some time and then the clock starts ticking again. The signal my_prio [rx_prio] is asserted after the clock gating but again within 100 clock cycles. other providersWebJan 5, 2011 · Clock-gating can be inserted automatically at systhesis level.
