Assertions in SystemVerilog Immediate and Concurrent

WitrynaExample 1 — Immediate assertion with an optional fail statement The assert...else immediate assertion is similar to an if...else, in that it executes as a programming statement at the moment in simulation time the statement is encountered (every positive edge of clock when resetN is high, in the example above).

Our sequence should thus be a throughout b [-&gt;1]. The throughout sequence will end when b goes high. At this point we need to check that a goes low on the next cycle: ##1 !a.
