Abstract

Aging is known to impact electronic systems affecting performance and reliability. However, it has been shown that it also brings benefits for power saving and area optimization. This paper presents highlights of those benefits and further shows how aging effects can be leveraged by novel methods to contribute towards improving hardware oriented security and reliability of electronic circuits. We have demonstrated static power reduction in complex circuits from IWLS05 benchmark suite, reaching a noticeable 7S% of reduction in ten years of operation. In hardware oriented security, a novel aging sensor has been proposed for detection of recycled ICs, measuring discharge time Tdv of the virtual power (VV dd) network in power-gated designs. This sensor utilizes discharge time of VVdd network through leakage current that is much more sensitive to aging than path delay, exhibiting up to 15.7X increment in 10 years. Furthermore, we show how frequency degradation caused by aging is used for online prediction of remaining useful lifetime (RUL) of electronic circuits. Results show an average RUL prediction deviation of less than 0.1 years. This methodology provides node calculations rather than a mean time to failure (MTTF) of the population. The set of techniques that are presented in this paper takes advantage of aging effects, having a positive impact in various aspects of microelectronic systems.
