Operator Library: Signal
The operator SignalEdge generates a pulse of one design clock cycle when it detects a level changing of the input signal. The parameter Edge specifies the type of the detecting edge. Three settings are possible:
-
Rising:
A pulse for each rising edge at the input is generated.
-
Falling:
A pulse for each falling edge at the input is generated.
-
Both:
A pulse for both, rising and falling edges at the input is generated.
This operator is excluded from the VisualApplets functional simulation.
