Method Summary

boolean	cellInterfaceDeterminesUniqueNetlistStructure() When false, the default behavior of this method, each cell will list itself separately in a netlist, guaranteeing that the netlist will not have invalid data at the expense of a larger file-size.
protected void	connectImplicitPorts() Connects the implicit ports.
protected boolean	defaultSimulationModelIsBehavioral() The default simulation model is structural for Structural cells.
BV[]	fetchBVState()
int[]	fetchState() This method is used to fetch the current state of the Cell.
java.lang.String	getCellName() Access the cell name associated with a derived class.
java.io.Serializable	getData() Called by the checkpointing code to get all of the data that should be checkpointed.
int	getSize(int wid, int aWid)
boolean	isNetlistLeaf() A few rare cells are leafCells during netlisting, but not during simulation.
void	setData(java.io.Serializable data) This is called on a checkpoint restore, and the object checkpointed out is passed back in.
void	updateState(int[] update_value) This method is used to update the state of the Cell in simulator.

Method Detail

connectImplicitPorts

protected void connectImplicitPorts()

Description copied from class: Logic

Connects the implicit ports. Override this if you shadow #implicit_ports. If you used the old version of connect_implicit_ports, this method will use reflection to see that the old version gets called correctly.

Overrides:

connectImplicitPorts in class Logic

getCellName

public java.lang.String getCellName()

Description copied from class: Cell

Access the cell name associated with a derived class. The cellname field is lazily evaluated on the first call of this method. Can be overriden to make cellname different by instance. If the field does not exist, this defaults to the classname.

Overrides:

getCellName in class Cell

Returns:

the cell name associated with a derived class, null if not declared.

isNetlistLeaf

public boolean isNetlistLeaf()

Description copied from class: Cell

A few rare cells are leafCells during netlisting, but not during simulation. Overriding this method should allow that behavior.

Overrides:

isNetlistLeaf in class Cell

Returns:

true is this cell is a leaf during netlisting, false otherwise.

cellInterfaceDeterminesUniqueNetlistStructure

public final boolean cellInterfaceDeterminesUniqueNetlistStructure()

Description copied from class: Cell

When false, the default behavior of this method, each cell will list itself separately in a netlist, guaranteeing that the netlist will not have invalid data at the expense of a larger file-size. Overriding this method to return true allows JHDL to save memory and netlists to be smaller by sharing the netlist structures that are guaranteed to be identical. NOTE: Do not override this unless every possible condition responsible for structural differences in a class (types and amount of children cells created, and arrangements of wires connected to ports) is included in the cellInterface[] of that class.

Overrides:

cellInterfaceDeterminesUniqueNetlistStructure in class Cell

Returns:

false if not overridden, preventing all memory sharing

defaultSimulationModelIsBehavioral

protected boolean defaultSimulationModelIsBehavioral()

Description copied from class: Structural

The default simulation model is structural for Structural cells. If the default should be behavioral, the user will need to overload this method to return true in cases besides TestBenches or leaf cells.

Overrides:

defaultSimulationModelIsBehavioral in class Structural

Returns:

true if TestBench or leafCell, false otherwise.

updateState

public void updateState(int[] update_value)

Description copied from interface: LargeExternallyUpdateable

This method is used to update the state of the Cell in simulator.

Specified by:

updateState in interface LargeExternallyUpdateable

Parameters:

update_value - the state to update to

fetchState

public int[] fetchState()

Description copied from interface: LargeExternallyUpdateable

This method is used to fetch the current state of the Cell.

Specified by:

fetchState in interface LargeExternallyUpdateable

Returns:

the current state

fetchBVState

public BV[] fetchBVState()

getData

public java.io.Serializable getData()

Description copied from interface: Checkpointable

Called by the checkpointing code to get all of the data that should be checkpointed. The data in the object returned should include all literal values last "put" onto all output wires, and any internal state that must be saved

Specified by:

getData in interface Checkpointable

Returns:

all state to be saved

setData

public void setData(java.io.Serializable data)

Description copied from interface: Checkpointable

This is called on a checkpoint restore, and the object checkpointed out is passed back in. In this function it is the responsibility of the circuit to do "put"s on all output wires using the *literal* (non-calculated) values checkpointed.

Specified by:

setData in interface Checkpointable

Parameters:

data - the state that was saved earlier

getSize

public int getSize(int wid,
                   int aWid)
