"Witryna8 cze 2015 · Here we'll use the throughout operator. The sequence "until b is asserted" is expressed as b [->1]. This is equivalent to !b [*] ##1 b. Our sequence should thus be a throughout b [->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.
