Abstract

See full text

A method, system, and computer program product to perform dynamic voltage frequency scaling of an integrated circuit include performing statistical timing analysis using a canonical form of a clock, the canonical form of the clock being a function of variability in voltage. Obtaining a canonical model expressing timing slack at each test location of the integrated circuit is as a function of one or more sources of variability, one of the one or more sources of variability being voltage, and performing the dynamic voltage-frequency scaling based on selecting at least one of a clock period and the voltage using the canonical model.
