Method Summary

void	configure() create and display a 'ConfigDialog' to set the parameters for a SimObject.
void	constructPorts()
void	evaluate(java.lang.Object arg) evaluate(): called by the simulation engine on all events that concern this object.
int	getShiftcount()

Constructor Detail

GenericShifter

public GenericShifter()

Method Detail

constructPorts

public void constructPorts()

Overrides:

constructPorts in class GenericRtlibObject

setSymbol

public void setSymbol(Symbol s)

Overrides:

setSymbol in class GenericRtlibObject

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 object argument

getShiftcount

public int getShiftcount()

setShiftcount

public void setShiftcount(java.lang.String s)

updateSymbol

public void updateSymbol()

Overrides:

updateSymbol in class GenericRtlibObject

write

public void write(java.io.PrintWriter ps)

write the following data to PrintWriter ps: our versionId, the width (n_bits), the shift count, the default output value (vector), and the default delay.

Overrides:

write in class GenericRtlibObject

initialize

public boolean initialize(java.lang.String s)

initialize an GenericShifter from a String which contains the integer version id, the width of the input vector, the shift count, a String of the desired start value (e.g. "1001 8 01ZXW001" for an 8 bit vector), and the default delay.

Overrides:

initialize in class GenericRtlibObject

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 GenericRtlibObject
