Claim:
1. A system for measuring sub-circuit level dynamic power static power, and uncorrelated residual power dissipated in an actual chip that contains multiple sub-circuits, each sub-circuit made of group of gates with one or more inputs, the system comprising: signal transition sensors connected to only to inputs of each sub-circuit and configured to count the number of signal transitions at each input or to time the duration of a signal transition at each input; a data storage system configured to store weight information indicative of an amount of dynamic power that is being consumed by each sub-circuit based on a count that is counted by or a time duration that is timed by each signal transition sensor that is connected to the inputs of that sub-circuit; a data storage system configured to store static power information indicative of the total static power that is being consumed by the digital circuit; a power consumption computation system configured to clean the measured power by extracting residual factors, including uncorrelated power consumption of a digital circuit and measurement noise from a measured power; a power consumption computation system configured to:
