public class ClockThread

extends SimulatorThread

This thread should be used from GUIs to execute steps or cycles of the simulator. This is important especially for long simulation runs that would otherwise lock up the GUI. If this Thread is used for any of the simulation control, it should be used for all of it. Also, to be sure that Stimulator events (puts to wires) are executed in the proper order relative to Clock events, make sure that you use StimulatorThreads as well.

It is crucial to note that ClockThreads are queued (in the SimulatorThread queue) in the order they are created, not necessarily in the order they are started by the creating thread.
