Abstract
An integrated circuit includes a plurality of tiles receiving a power supply voltage, each having a corresponding analog circuit and operates in response to a first voltage, and a hardware controller receiving a voltage identification code and provides the first voltage to each of the plurality of tiles in response thereto. The hardware controller comprises a test time controller determining coefficients of a waveform that describes an average correspondence between the power supply voltage and the first voltage for the plurality of tiles, and a boot time controller determining a respective error signal indicating an error between the waveform and a respective actual waveform for each of the plurality of tiles, and providing the respective error signal to the corresponding analog circuit of each of the plurality of tiles. The corresponding analog circuit of each of the plurality of tiles adjusts the first voltage according to the respective error signal.
