A consumption current measurement approach for FPGA based embedded systems

An approach for field programmable gate array (FPGA) based embedded system dynamic current consumption measurement is presented in the paper. The measurement method is based on current conversion to time interval. The time interval is then measured using timer implemented in FPGA. Measurement uncertainty budget analysis is performed. It reveals key components and their parameters mostly affecting current measurement uncertainty. System architecture for incorporating measurement setup to the standard FPGA development flow is suggested.
