That means you need to count up to 25e6 (or (25e6)-1, depending how you set it up), reset the counter back to zero, and begin counting again. Every time your counter reaches 0 (or 25e6, or any other single value in the count), you can pulse an enable for one clock cycle.

Web21 Aug 2024 · If there is a transition in clock enable signal when the clock signal is low, there is no effect on the gated clock. But if there is a transition in clock enable signal when the clock signal is high, there will be a glitch in the gated clock. To suppress such glitches, latch-and gate based ICG cell is preferred.
