Method Detail

evaluate

public void evaluate(java.lang.Object arg)

evaluate(): read the current input Port values and calculate the corresponding seven-segment output values. Note that this class also checks for power-supply at the VCC and GND inputs, in order to simulate the "real" integrated circuit.
