1. A method for power supply voltage drop compensation within an integrated circuit, the method comprises:

  • providing a supply voltage to the integrated circuit;

    sampling voltage levels at multiple sampling points located at different locations within the integrated circuit, to provide multiple sampled voltages, wherein the multiple sampled voltages reflect the voltage drops at the multiple sampling points;

    selecting a subset of sampled voltages out of the multiple sampled voltages, the subset not including a first voltage of the multiple sampled voltages; and

    adjusting a voltage supply provided to the integrated circuit based on the subset of sampled voltages, and not based on the first voltage.
