This paper presents a new approach on aging sensors for synchronous digital circuits. An adaptive error-prediction flip-flop architecture with built-in aging sensor is proposed, performing on-line monitoring of long-term performance degradation of CMOS digital systems. The main advantage is that the sensor's performance degradation works in favor of the predictive error detection. The sensor is out...
The purpose of this paper is to present a predictive error detection methodology, based on monitoring of long-term performance degradation of semiconductor systems. Delay variation is used to sense timing degradation due to aging (namely, due to NBTI), or to physical defects activated by long lifetime operation, which may occur in safety-critical systems (automotive, health, space). Error is prevented...
The implementation of complex functionality in low-power nano-CMOS technologies leads to enhance susceptibility to parametric disturbances (environmental, and operation-dependent). The purpose of this paper is to present recent improvements on a methodology to exploit power-supply voltage and temperature variations in order to produce fault-tolerant structural solutions. First, the proposed methodology...
