All Implemented Interfaces:

java.lang.Cloneable, ContextToolTip, java.io.Serializable, Simulatable

public class RomDiode

extends GenericGate

implements Simulatable

RomDiode: a faked diode useful for demonstrating ROM or PLA arrays. This model uses the std_logic levels to simulate a diode-like behaviour; however, we use a fixed input-output assignment. A logical 1 at the kathode input will result in a 1 output, while other input values result in a Z output value.
