Abstract: Aspects of dynamic power profiling are described herein. In various embodiments, a current sense operating mode is set for a current sense circuit, and the current sense circuit is enabled for operation. The current sense circuit senses an amount of current supplied by at least one of a plurality of power rails based on the current sense operating mode. The current sense circuit also accumulates and stores a value of the amount of current over a period of time. In certain aspects, a system controller averages the value of the amount of current based on the period of time. The current sense circuit may be configured to operate in various modes of operation including single or scan rail modes of operation, and the average of the value of the amount of current may be evaluated based on the modes of operation of the current sense circuit and/or the system.
