II.3.7. Diary

When active, this facility opens a new MATLAB window (fig. II.11) that displays (dynamically - during the simulation) the instant(s) when the next fireable transition(s) is (are) to fire. For several fireable transitions, the displayed list of transitions is ordered by the instants when the firings will occur.

The Diary facility is available only in the Step and Run Slow simulation modes. The usage of this facility is recommended for timed PN models and it gives no relevant information in the case of untimed models.
