Abstract
A system may include acquisition of a supply voltage information representing past supply voltages supplied to an electrical component, acquisition of a temperature information representing past temperatures of the electrical component, and control of a performance characteristic of the electrical component based on the supply voltage information and the temperature information. Some embodiments may further include determination of a reliability margin based on the supply voltage information, the temperature information, and on a reliability specification of the electrical component, and change of the performance characteristic based on the reliability margin.
