Abstract
Low-impedance pins are electrically connected to a set of corresponding nodes of a multi-phase VRM. The multi-phase VRM is activated. A failure condition is induced in a phase of the multi-phase VRM by modifying operating parameters of the phase of the multi-phase VRM using the set of low-impedance pins. The output signal of the multi-phase VRM is monitored in response to the induced failure condition.
