Pulse Generator
The behavior of the Pulse Generator is defined by their delay and width. The delay is the
amount of time the pulse is inactive prior to the pulse, and the width is the amount of time
the pulse is active.
The Pulse Generator signals can be set in either triggered or periodic mode. In triggered
mode, the pulse generator is triggered by either the rising edge or high level of the input
signal. When triggered, the pulse generator is inactive for the duration of the delay, then
active for the duration of the width. After that, it will become inactive until the next trigger
occurs. If a trigger occurs while pulse generator is already handling a previous trigger, the
new trigger is ignored.
In periodic mode, the trigger continuously generates a signal that is based on the
configured delay and width. The period of the pulse is therefore the delay time plus the
width time.

Width
Indicates the number of cycles (also determined by the granularity) that the pulse remains
at a high level before falling to a low level.
