It waits for signal “gnt” to be high for 5 clock cycles, followed by signal “enable” not asserted high, and hence, the assertion fails. This behavior is the same as “Go to repetition”. 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. greek islands list with airports
