WebJun 5, 2024 · You should have a different assertion that checks that req should stay 1. This will make it easier to debug, because you split checks for valid from checks for req and ack. Putting it all together, the assertion should look like: WebOnce again, just as any other construct of concurrent assertion, all evaluations of expressions or sequence matching is done only at a clock edge. Evaluation or matching has no meaning in between two clock edges. As shown in Figure 2, the match operators are and, intersect, or, throughout, and within. We discuss each of them below.
