public class PulseSwitch

extends Ipin

implements Simulatable, Wakeable, Assignable

PulseSwitch - a simple subclass of Ipin that models an 'pulse' switch. Also, a PulseSwitch object is automatically interpreted as an input for a hierarchical Design - like a standard-CAD 'ipin'.

The default pulse duration is 0.1 seconds.

Method Detail

getPulseDuration

public double getPulseDuration()

setPulseDuration

public void setPulseDuration(double t)

setPulseDuration

public void setPulseDuration(java.lang.String s)

mousePressed

public void mousePressed(java.awt.event.MouseEvent me)

Description copied from class: Ipin

handle a mouse click on this IpinWithBindkey's graphical symbol. Toggle the Ipin output value, schedule a corresponding output event with the new output value, and update the graphical symbol. For a normal mouse-click, the output value toggles between "0-1-0...", while a shift-mouse-click toggles between "0-1-Z-U-0..." states.

Overrides:

mousePressed in class Ipin

keyPressed

public void keyPressed(java.awt.event.KeyEvent ke)

Description copied from class: SimObject

react to a KeyEvent. The base SimObject ignores all KeyEvents. this method is currently only used by a few classes in hades.models.io, e.g. IpinWithBindkey.

At the moment this is actually called from KeyHandler.keyTyped(), but this naming mismatch is not considered critical...

Overrides:

keyPressed in class Ipin

mouseOrKeyPressed

public void mouseOrKeyPressed(boolean isShiftDown)

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 Ipin

Parameters:

arg - This parameter is ignored by PulseSwitch

evaluate

public void evaluate(java.lang.Object arg)

evaluate(): called by the simulation engine on all events that concern this object. For a PulseSwitch, these are events from a toplevel design. We simply dispatch to Ipin.evaluate().

Specified by:

evaluate in interface Simulatable

Overrides:

evaluate in class Ipin

configure

public void configure()

Description copied from class: Ipin

configure: display a dialog to specify the Ipin instance name, initial output value, and gate propagation delay.

Overrides:

configure in class Ipin

write

public void write(java.io.PrintWriter ps)

Description copied from class: Ipin

write the versionID and the start value of this Ipin (the latter as StdLogic1164.getChar() value), e.g. "1001 Z"

Overrides:

write in class Ipin

initialize

public boolean initialize(java.lang.String s)

initialize an Ipin from a String, which contains the integer version id, and optionally the pulse width (in seconds).

Overrides:

initialize in class Ipin

toString

public java.lang.String toString()

toString() - the usual info method

Overrides:

toString in class SimObject
