  • Publication number: 20060001100
    Abstract: A method for simulating an electrostatic discharge protective circuit replaces an electrostatic discharge protective element having an insulated-gate field-effect transistor having a source and a drain with an equivalent circuit including the insulated-gate field-effect transistor, a bipolar transistor, a current source, a diode, and a substrate resistance. Then, the method applies a forward bias to the source or the drain to perform a first simulation with respect to the equivalent circuit and applies a reverse bias to the source or the drain to perform a second simulation with respect to the equivalent circuit. The diode is disposed to cause, when the forward bias is applied to the source or the drain, a forward diode current to flow to the source or the drain to which the forward bias has been applied.
