trig_time :
A trigger generator for timed events.

The trig_time primitive generates an xbit-typed trigger out at specified time instants. For instance, the parameters delay and period specify that the primitive shall trigger out when time is equal to delay + N*period, where N is 0, 1, 2, … If delay is less than 0, the primitive triggers out at the end of simulation. If period is less than or equal to 0, the primitive triggers out only once. Alternatively, one can set the list of time instants at which the primitive shall trigger out using the parameter data.

The xbit-typed trigger out can be used as an input to the measurement primitives to measure the time instants, delays, periods, etc. of the triggering events. The trigger signal is initialized to X and changes to 1 when the first event occurs. The trigger output out then toggles to a different value (0 or 1) whenever a subsequent event occurs.
