    Abstract: Embodiments herein relate to a chiplet or other die which includes multiple sense points within the die and components for digitizing and outputting sensed voltages of the sense points. In one approach, an analog-to-digital converter (ADC) is coupled to each sense point, and a multiplexer is coupled to the outputs of the ADCs. A select signal for the multiplexer can be received from an external control unit which selects one of the sense points based on information such as a current workflow of the die. The selected sense point can change as the workflow changes. The optimal sense point can be determined by comparing the voltage of each sense point and selecting the sense point with the lowest voltage. The sensed voltage is provided to a voltage regulator as a feedback signal to optimize control of the power supply of the die.
