The availability and efficiency of reliability simulators for analog ICs is becoming critical with the scaling of devices down to the nanometer nodes. Two of the main challenges here are how to simultaneously include different sources of unreliability (such as the time-zero or spatial variability and the aging or time-dependent variability), and how to account for the self-induced changes in device...
Variability is one of the main and critical challenges introduced by the continuous scaling in integrated technologies and the need for reliable ICs. In this regard, it is necessary to take into account time-zero (i.e., spatial or process variability) and time-dependent variability (i.e., aging). While process variability has been extensively treated, considerable efforts are currently being made...
Present and future semiconductor technologies are characterized by increasing parameters variations as well as an increasing susceptibility to external disturbances. Transient errors during system operation are no longer restricted to memories but also affect random logic, and a robust design becomes mandatory to ensure a reliable system operation. Self-checking circuits rely on redundancy to detect...
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...
With technology scaling, vulnerability to soft errors in random logic is increasing. There is a need for on-line error detection and protection for logic gates even at sea level. The error checker is the key element for an on-line detection mechanism. We compare three different checkers for error detection from the point of view of area, power and false error detection rates. We find that the double...
