Method Detail

elaborate

public void elaborate(java.lang.Object arg)

elaborate(): This method is called by the simulation engine to initialize the simulation object. We schedule "U" values on all outputs Y1, ... Y6 at time t=0.0 seconds.

Specified by:

elaborate in interface Simulatable

Overrides:

elaborate in class SimObject

evaluate

public void evaluate(java.lang.Object arg)

evaluate(): extract the active Port from the SimEvent argument and calculate the corresponding open-collector INV output.

Specified by:

evaluate in interface Simulatable

Overrides:

evaluate in class SimObject

Parameters:

arg - an arbitrary object argument

schedule

public void schedule(Port port_Y,
                     Port port_A,
                     double time)

model open-collector inverter

schedule

public void schedule(Port target,
                     StdLogic1164 value,
                     double time)

getValueOrU

public StdLogic1164 getValueOrU(Port p)

toString

public java.lang.String toString()

toString() - the usual info method

Overrides:

toString in class SimObject
