Abstract
A design verification system simulates operation of an electronic device to identify one or more power characteristic vs. temperature (PC-T) curves for the electronic device. Each of the one or more PC-T curves indicates, for a particular reliability characteristic limit, a range of power characteristic values over a corresponding range of temperatures that are not expected to result in the reliability characteristic limit being exceeded. Based on the one or more PC-T curves, the design verification system sets a range of power characteristic limits, over a corresponding range of temperatures, for the electronic device. During operation, the electronic device employs a temperature sensor to measure an ambient or device temperature, and sets its power characteristic (voltage or current) according to the measured temperature and the power characteristic limits.
