Class Constant

java.lang.Object
  hades.simulator.SimObject
      hades.models.io.Constant

All Implemented Interfaces:

java.lang.Cloneable, ContextToolTip, java.io.Serializable, Simulatable

Direct Known Subclasses:

public class Constant

extends SimObject

implements Simulatable, java.io.Serializable

Constant - common subclass for Constant_0, Constant_1, Constant_H, etc., that is, simulation models that generate constant StdLogic1164 values. Signals are expected to be StdLogic1164 objects.

Method Summary

void	elaborate(java.lang.Object arg) elaborate: If our output signal is non-null, we schedule an SimEvent at the current simulation time, in order to initialize the Signal with the value Constant ('0').
void	evaluate(java.lang.Object arg) evaluate: As a Constant-Object, we will schedule a new 'Constant' value, whenever the Signal might have changed.
