circuit

protected Cell circuit

Pointer to the Cell that is currently being drawn.

_viewport

protected javax.swing.JViewport _viewport

A reference to any viewport that may be controlling this Component. Instead of hardcoding this JPanel to a CircuitView, this object will keep a reference to any viewport. The viewport is needed to perform offset calculations when mouse clicks are made onto a portion of the shown schematic. TODO: allow _viewport to be a null (i.e. a panel not inside a viewport). in these cases, ignore all mouse issues that require the viewport.

defaultRadix

protected static final BVFormat defaultRadix

This is the String to initialize the BVFormatradix for wire values.

_schematicActionListeners

radixFormat

protected BVFormat radixFormat

scaledPrintTransform

protected java.awt.geom.AffineTransform scaledPrintTransform

Because the Printable.print() method is called twice for each page and the first time it is called doesn't have the proper scale information for the printer, this AffineTransform is used to remember the scaled transform. This way, when a certain page is requested, then we can use the stored scaled transform to calculate whether the requested page exists or not.

printScaleX

protected double printScaleX

Stores the horizontal scale factor associated with the stored scaledPrintTransform

printScaleY

protected double printScaleY

Stores the vertical scale factor associated with the stored scaledPrintTransform

zoom

public void zoom(double zoom)

Perform a zoom in or out on the schematic.

Parameters:

zoom - The zoom value of the component (must be positive). A value of 1.0 indicates the baseline. This method queries the viewport to calculate the new viewport position.

simulatorRefresh

public void simulatorRefresh(int cycle,
                             int phase)

Description copied from interface: SimulatorCallback

This method is called after each simulation run. A simulation run is a multiple clock/step execution issued by a testbench or jab. For example, if the user types 'cycle 50', this callback method will be called after the completed simulation of all 50 clock cycles. Unlike the simulatorUpdate method, this method will not be called on each simulation event. This method is useful for GUIs or display widgets that only need to be updated once the simulaton has paused.

Specified by:

simulatorRefresh in interface SimulatorCallback

Parameters:

cycle - The current cycle number of the simulator. This value is the same as the value generated by the call HWSystem.getTotalClockCount().

phase - The current phase of the simulator. This value is the same as the value generated by the call HWSystem.getCurrentStepCount().

simulatorUpdate

public void simulatorUpdate(int cycle,
                            int phase)

Description copied from interface: SimulatorCallback

This method is called after each simulation event. The granularity of the event is determined by the specific Simulator within the simulate() method of the Simulator. For the single-clock simulator, this corresponds to each cycle of simulation. For the multi-clock simulator, this corresponds to each step in the clock schedule of the simulator.

Specified by:

simulatorUpdate in interface SimulatorCallback

Parameters:

cycle - The current cycle number of the simulator. This value is the same as the value generated by the call HWSystem.getTotalClockCount().

phase - The current phase of the simulator. This value is the same as the value generated by the call HWSystem.getCurrentStepCount().

simulatorReset

public void simulatorReset()

Description copied from interface: SimulatorCallback

This method will be called after the simulation has been reset. Unlike the initialize method of the Initializeable interface, this method is called after every simulator reset. This method can be used to reset variables associated with watching the progress of a simulation. Note that the cycle and phase number is reset to zero before this call is made.

Specified by:

simulatorReset in interface SimulatorCallback
