Abstract
Techniques for enhancing the performance of an IC are provided. A method of enhancing IC performance includes the steps of: associating at least one performance result of at least one performance monitor, formed on the IC, with deterministic combinations of IC performance and a processing parameter, a supply voltage, and/or a temperature of the IC; determining an IC processing characterization of the IC as a function of the performance result for at least one prescribed supply voltage and temperature of the IC, the IC processing characterization being indicative of a type of processing received by the IC during fabrication of the IC; and controlling a voltage supplied to at least a portion of the IC, the voltage being controlled as a function of the IC processing characterization and/or the temperature of the IC so as to satisfy at least one prescribed performance parameter of the IC.
