public class GenericOnebitLogicObject

extends SimObject

implements Simulatable, Wakeable, java.io.Serializable

GenericOnebitLogicObject - the utility base class for HADES n-to-1 bit logical RTLIB models,

This class supplies a generic configuration dialog with object name, input bus width (n_bits), default output value, default delay.

Input Signals are expected to be SignalStdLogicVector objects with n_bits bits, output Signals are of type SignalStdLogic1164.

constructPorts

getDelay

public double getDelay()

setDelay

public void setDelay(double _delay)

public int getWidth()

public void setWidth(int _n)

public long getValue()

setValue

setValue

public void setValue(java.lang.String s)

isConnected

public boolean isConnected()

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

initValueLabel

protected void initValueLabel()

updateSymbol

public void updateSymbol()

elaborate

public void elaborate(java.lang.Object arg)

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

GenericOnebitLogicObject just calls updateSymbol() to initialize its graphical representation. Probably, most RTLIB classes won't need to override this method.

Specified by:

elaborate in interface Simulatable

Overrides:

elaborate in class SimObject

wakeup

public void wakeup(java.lang.Object arg)

wakeup(): Called by the simulator as a reaction to our own scheduleWakeup()-calls. For RTLIB components, a wakeup() is normally used to update the value label

Specified by:

wakeup in interface Wakeable

initialize

public boolean initialize(java.lang.String s)

initialize a RTLIB object from a String which contains the integer version id, the width of this vector, the desired start value, and the default delay (e.g. "1001 8 U 0.3E-9" for an 8 bit vector).

Overrides:

initialize in class SimObject

write

public void write(java.io.PrintWriter ps)

write the following data to PrintWriter ps: our versionId, the width (n_bits), the default output value (vector), and the default delay. Hopefully, many RTLIB classes won't need to override write().

Overrides:

write in class SimObject

copy

public SimObject copy()

copy(): This function is used to create a clone of this RTLIB object, including the values for width (n_bits), currenct value (vector), propagation delay, and version ID.

Overrides:

copy in class SimObject

toString

public java.lang.String toString()

Description copied from class: SimObject

toString: generate a text description for this SimObject. This method currently combines the class name for the SimObject (or subclass) and its full name in the current Hades Design, e.g. "hades.models.gates.And2: /uut/adder16/adder1/i3".

Overrides:

toString in class SimObject
