Abstract
A system-on-a-chip includes an integrated circuit and an estimation circuit. The estimation circuit operates to acquire at least one physical parameter representative of the use of the integrated circuit and determine an instantaneous state of aging of the integrated circuit as a function of the at least one physical parameter. A margin of use of the integrated circuit is then calculated by comparing the instantaneous state of aging with a presumed state of aging.
