Simulation Step

A simulation step is a change in the system status in response to external stimuli or internal changes. A step can be triggered by an action (internal or external) or the trigger can be a timeout event occurring as a result of incrementing time.

A simulation step is a two stage process; it occurs as follows:

When the simulation execution begins, and before the first step is performed, the default initial status of the system is:

After the first simulation step is taken, the system status is:

All other elements of the system status are modified in accordance with actions performed on default connectors or by static reactions on entrances into these states.
