1. A method for power supply optimization of an integrated circuit, comprising:

  • determining an analog variation parameter representative of an integrated circuit fabrication process variance of the integrated circuit;

    determining an operational temperature associated with the analog variation parameter; and

    determining an adjustment signal for a power supply voltage level of the integrated circuit based on the analog variation parameter with respect to the operational temperature; and

    adjusting a regulation signal of a DC-to-DC converter based on the adjustment signal to optimize power consumption of the integrated circuit.
