Operator Library: Signal
The operator's signal link output can be set by software using parameter Mode. The state type is specified by the parameter Mode. Three options are available:
-
Low:
The operator output signal link has low value (zero).
-
High:
The operator output signal link has high value (one).
-
Pulse:
The operator will generate a pulse at its output, i.e. will output a high value for one clock cycle. After this pulse, the operator will output low value (zero). Setting the parameter to Pulse after it was set to High will not generate a low value before the pulse. Hence, the parameter should be set to Low or Pulse before setting it to Pulse.
This operator is excluded from the VisualApplets functional simulation.
