WebJun 22, 2024 · Once ack is true, it should de-assert the very next clock. My test starts with $rose (req); then keep !req asserted for a few clocks (less than 10) and then drives ack=1. Then, I keep ack=1 for 4 clocks. It does not go low the very next clock, as the assertion requires. Still, the assertion does not fail.
