A method for detecting a missing or defective power supply pin connection or other defect that results in excessive transient voltages on power supply rails of a circuit comprises applying a dc voltage, whose level is substantially independent of transient voltages on the supply voltage rails, to a sensor logic gate whose output is applied to a latching circuit, applying a signal transition to a stimulus logic gate that is connected to the supply voltage rail; and monitoring the output of a latching circuit for a change in state, a change of state indicating a missing or defective power supply pin connection or other such defect.
