WebAug 10, 2024 · This is resulting in false assertion failure at reset release; as the disabling of res_en and release of reset happens at the same time in design, where-as throughout expects it to happen after a cycle delay. Need help to get it resolved. Reset enable: res_en. Reset signal: reset_n. clock: ref_clk. WebJan 20, 2015 · Think of a clock gate as "simple and" with an enable gating the clock. The reason you do this is to stop unnecessary toggles on the clock pin of flops. Even if the output doesn't toggle, the internal flop circuitry dissipates unnecessary power. Power saving can be achieved by simply gating the clock with an enable.
