Abstract
Power consumed by a digital circuit that contains multiple sub-circuits may be computed. Each sub-circuit may include more than one transistor and have at least one input. A signal transition sensor may be connected to an input to each sub-circuit and configured to count the number of signal transitions at the input or to time the duration of a signal transition at the input. Weight information may be stored that is indicative of an amount of 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 an input of that sub-circuit. The amount of power being consumed by the digital circuit may be computed based on a count that is counted by or a time duration that is timed by each signal transition sensor and the weight information.
