  text: Time-variant age information of different parts of a system can be used for
    system-level performance improvement through high-level task scheduling, thus
    extending the life-time of the system. Progressive age information should provide
    the age state that the system is in, and the rate that it is being aged at. In
    this paper, we propose a structure that monitors certain paths of a circuit and
    detects its gradual age growth, and provides the aging rate and aging state of
    the circuit. The proposed monitors are placed on a selected set of nodes that
    represent a timing bottleneck of the system. These monitors sample expected data
    on these nodes, and compare them with the expected values. The timing of sampling
    changes as the circuit ages and its delay increases. The timing of sampling will
    provide a measure of aging advancement of a circuit. To assess the efficacy of
    the proposed method and compare it with other state-of-the-art aging monitors,
    we use them on selected nodes of the execution unit of different processors, as
    well as some circuits from ITC99 benchmarks. The results reveal that the precision
    of our proposed method is between 0.12 (ns) to 0.401 (ns). Its Area and power
    overhead are negligible and are about 2.13 and 0.69 percent respectively.
