WebJun 26, 2024 · Clock gating, though it is a good power management method, is a bit challenge to utilize its full capability. Traditional clock gate placement guideline includes carefully selected design WebMay 8, 2024 · For clock trees, the traditional way is to go with zero skew or balanced skew. For each of the sinks, the insertion delay is kept to be equal so that each node receives the clock at the same time (or as close as physically possible). Here, your clock design is completely independent of your data path design.

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. WebClock gating is used to save dynamic power.
