Abstract
Methods and systems for integrated circuit design using dynamic voltage scaling may comprise (a) designing an IC to meet a voltage dependent frequency specification, the IC design including feedback circuitry for controlling a power supply voltage to a fabricated instance of the IC design, (b) characterizing a fabrication process for corner lots for the IC design at a range of power supply voltage levels achievable by the feedback circuitry; (c) validating the IC design against the fabrication process if the frequency specification is achievable for essentially all instances of the IC design fabricated, wherein the feedback circuitry in each IC resulting from the IC design is operable to respectively adjust the power supply voltage of each IC resulting from the IC design by reducing the power supply voltage if the IC is from a fast corner lot and increasing power supply voltage if from a slow corner lot.
