A method and apparatus for adaptively adjusting the operating voltage of an integrated circuit in response to tester-to-system variations, worst-case testing techniques, process variations, temperature variations, or reliability wearout mechanisms. The minimum operating voltage of an integrated circuit is determined either during external testing of the integrated circuit or during built-in-self-testing. The minimum operating voltage is transmitted to a variable voltage regulator where it is used to set the output of the regulator. The output of the regulator supplies the integrated circuit with its operating voltage. This technique enables tailoring of the operating voltage of integrated circuits on a part-by-part basis which results in power consumption optimization by adapting operating voltage in response to tester-to-system variations, worst-case testing techniques, process variations, temperature variations or reliability wearout mechanisms.

A probe card provides signal paths between integrated circuit (IC) tester channels and probes accessing input and output pads of ICs to be tested. When a single tester channel is to access multiple (N) IC pads, the probe card provides a branching path linking the channel to each of the N IC input pads. Each branch of the test signal distribution path includes a resistor for isolating the IC input pad accessed via that branch from all other branches of the path so that a fault on that IC pad does not substantially affect the voltage of signals appearing on any other IC pad. When a single tester channel is to monitor output signals produced at N IC pads, the resistance in each branch of the signal path linking the pads of the tester channel is uniquely sized to that the voltage of the input signal supplied to the tester channel is a function of the combination of logic states of the signals produced at the N IC pads. The tester channel measures the voltage of its input signal so that the logic state of the signals produced at each of the N IC output pads can be determined from the measured voltage.
