Abstract: A system on a chip includes at least one integrated circuit that is configured to operate at least at one operating point. A monitoring circuit acquires at least the cumulative duration of activity of the at least one integrated circuit. An evaluation circuit establish at least one instantaneous state of aging of the at least one integrated circuit based on the at least one cumulative duration of activity. An adjustment circuit operates to change the at least one operating point on the basis of the at least one state of aging of the at least one integrated circuit.
