Abstract
A system and method for biasing supply voltage requirements that are input to a voltage regulator to facilitate testing a computer system with supply voltages above and below specified operating values. The present invention may also be used to compensate a voltage regulator that is not outputting the supply voltage required by the computer system. The system includes a processor voltage signal indicative of supply voltage required by one or more components in a computer system during operation, at least one other voltage signal indicative of margined or biased supply voltage for the computer system, and a selection control signal for selecting between the processor voltage signal and the at least one other voltage signal. The processor voltage signal, the at least one other voltage signal, and the selection control signal, are input to a multiplexer. The multiplexer outputs a voltage identification signal to the voltage regulator based on the processor voltage signal, the at least one other voltage signal, and the selection control signal.
