Abstract
A storage unit on an integrated circuit stores information that identifies a circuit on the integrated circuit, a selected operating condition, and a required operating configuration for the circuit for the selected operating condition. The manner of operating the circuit is changed to the required operating configuration in response to an operating condition of the circuit changing to the selected operating condition. This allows for efficiently identifying the few circuits that do not meet specified requirements based on a reduction in, for example, operating voltage, and altering their operation in order to meet the specified requirements relative to the reduced operating voltage without having to do so for the vast majority of the circuits that are able to meet the requirements at the lowered operating voltage.
