Abstract
A method for testing system-on-a-chip (SoC) for faults at subthreshold or substantially at threshold operating voltages includes the steps of testing the SoC for fault at a favorable operating voltage, the testing including measuring a metric characterizing the fault at the favorable operating voltage to obtain a first metric value; and retesting the SoC for the fault at a first operating voltage upon the first metric value at the favorable operating voltage being correlated, according to a metric correlation establishing a correlation relationship between the favorable operating voltage and the first operating voltage, to a second metric value at the first operating voltage within a predictive interval of the metric correlation.
