Abstract
A method for determining a margin of use of an integrated circuit includes monitoring at least one sensor so as to determine at least one physical parameter representative of use of the integrated circuit, evaluating the at least one physical parameter to determine an instantaneous state of aging of the integrated circuit as a function of the at least one physical parameter, and calculating the margin of use for the integrated circuit from a comparison of the instantaneous state of aging with a presumed state of aging. If operation of the integrated circuit is outside the margin of use, at least one operating performance point of the integrated circuit is adjusted so as to bring operation of the integrated circuit back within the margin of use.
