WebDec 19, 2024 · This will require some redesign of your state machine, since if you simply put a register in front of your AND gate, the read pulse will occur almost one clock cycle later than without the register. Therefore you will have to change the fan-in to your AND gate to select state 101 rather than what you currently have, which selects state 110. WebMar 28, 2016 · For coarse grained clock gating, you can imagine there is a tradeoff between how much logic you gate at once versus how complex the clock gating logic is. The more you gate at once, the simpler the logic, and vice versa.
