Class EdgeTrigger

java.lang.Object
  hades.simulator.SimObject
      hades.models.special.EdgeTrigger

All Implemented Interfaces:

java.lang.Cloneable, ContextToolTip, java.util.EventListener, java.awt.event.ItemListener, java.io.Serializable, Simulatable

public class EdgeTrigger

extends SimObject

implements Simulatable, java.awt.event.ItemListener

EdgeTrigger - a class to detect and react to selected edges (changes) on SignalStdLogic1164 signals.

For example, a EdgeTrigger object may be used as a 'breakpoint' which pauses the simulation on certain input value changes, e.g. a Z->0 transition.

public EdgeTrigger()

EdgeTrigger(): simple constructor

Method Detail

setSymbol

public void setSymbol(Symbol s)

Overrides:

setSymbol in class SimObject

buildEdgePanel

void buildEdgePanel()

buildActionPanel

void buildActionPanel()

buildButtonPanel

void buildButtonPanel()

buildGUI

public void buildGUI()

buildGUICallbacks

public void buildGUICallbacks()

itemStateChanged

public void itemStateChanged(java.awt.event.ItemEvent evt)

Specified by:

itemStateChanged in interface java.awt.event.ItemListener

changeName

public void changeName()

write

public void write(java.io.PrintWriter ps)

Overrides:

write in class SimObject

initialize

public boolean initialize(java.lang.String s)

Description copied from class: SimObject

initialize a SimObject from a String. The method returns true once all required data has been read. Until then, you should repeatedly call initialize() with additional Strings.

Overrides:

initialize in class SimObject

configure

public void configure()

Description copied from class: SimObject

create and display a 'ConfigDialog' to set the parameters for a SimObject. The default ConfigDialog for the base class (SimObject) itself is empty except for the 'instance name' of the SimObject.

Overrides:

configure in class SimObject

getPropertySheet

public java.awt.Component getPropertySheet()

Description copied from class: SimObject

return a reference to the 'property sheet' or configuration window for this SimObject. We cast the return value to an AWT Component, but typically you can expect either a hades.gui.PropertySheet or an java.awt.Window (Dialog or Frame).

Overrides:

getPropertySheet in class SimObject

elaborate

public void elaborate(java.lang.Object arg)

elaborate(): This method is called by the simulation engine to initialize the simulation object.

Specified by:

elaborate in interface Simulatable

Overrides:

elaborate in class SimObject

Parameters:

arg - This parameter is ignored by EdgeTrigger

getInputValue

public StdLogic1164 getInputValue(Port p)

evaluate

public void evaluate(java.lang.Object arg)

evaluate(): called by the simulation engine on all events that concern this object. The object is responsible for updating its internal state and for scheduling all pending output events.

Specified by:

evaluate in interface Simulatable

Overrides:

evaluate in class SimObject

Parameters:

arg - An arbitrary and unused object

match

public boolean match(StdLogic1164 value_A,
                     int intValue)

trigger

public void trigger(java.lang.Object arg)

formatPaddedLong

public static java.lang.String formatPaddedLong(long value,
                                                int n_chars)

copy

public SimObject copy()

copy(): create a clone of the current EdgeTrigger, including its color

Overrides:

copy in class SimObject

getToolTip

public java.lang.String getToolTip(java.awt.Point position,
                                   long millis)

Description copied from class: SimObject

construct a (short) tool tip message for a SimObject. This method should be overridden as needed.

Specified by:

getToolTip in interface ContextToolTip

Overrides:

getToolTip in class SimObject

toString

public java.lang.String toString()

toString() - the usual info method

Overrides:

toString in class SimObject

main

public static void main(java.lang.String[] argv)

main(): simple selftest of the EdgeTrigger's GUI
