1. A method for maintaining performance of an integrated circuit at a reduced power, the method comprising:

  • concurrently triggering a critical path of the integrated circuit and a performance monitor formed on the integrated circuit that generates a signal indicative of at least one performance characteristic of at least a portion of the critical path;

    determining a performance measurement of the performance monitor, which models at least one characteristic of the critical path, based on the triggering;

    adjusting the performance measurement to compensate for temperature offsets associated with performance of the performance monitor relative to performance of the critical path over different operating temperatures; and

    adjusting a supply voltage of the integrated circuit based on the adjusted performance measurement to maintain performance of the integrated circuit at a reduced power.
