At this stage GoAdvance is used to increment time.
1. Select Go > GoAdvance.
2. Enter the value 16 and click OK.Our design calls for the east-west light to remain green for 15 seconds. Since the clock has been advanced 16 seconds, the simulation informs you that there are reactions completed before the specified time. The east-west lights change from green to yellow and the clock is incremented the full 16 seconds.
