Claim 11:
12. A computer-implemented method, comprising:
analyzing, by a system operatively coupled to a processor and to one or more test circuits, the one or more test circuits operated at sub-threshold voltages, wherein the system that performs the analyzing comprises an electrical device configured to assess the electrical characteristics of the one or more test circuits;
generating, by the system, a current-voltage characteristic curve characterizing the operation of the one or more test circuits;
identifying, by the system, whether at least one of the one or more test circuits is an aged circuit by analyzing a current-voltage characteristic curve for a distortion in a sub-threshold quiescent current signature of the aged circuit, wherein the distortion is characterized by the formation of multiple peaks in the sub-threshold current measurement of the current-voltage characteristic curve;
generating, by a screen of a display connected to the system, a visual indicator of a location of the distortion on the current-voltage characteristic curve, wherein the visual indicator is generated by the display and output, via the screen of the display, to a user of the system;
transmitting, by the system, to one or more devices, from the system, via an electrical connection of one or more servers, data received at the system and employed to perform the identifying; and
identifying, by the system, the one or more test circuits as an aged circuit without reverse engineering and based on the current-voltage characteristic curve.
