WebFeb 9, 2024 · You are trying to sample the clock signal on the rising edge of itself. This violates Nyquist criterion since you are sampling the clock … To do this I have gated the clock: assign sync_gated = i_sync !r_en; This is combinational logic, but I don't see any issue as there is a full clock cycle (we run at 2MHz) for the output of the counter to settle. A few ns of propagation delay will not cause a problem. The code synthesises OK, but I get this warning:
