Fault tree analysis (FTA) is a prominent reliability analysis method widely used in safety-critical industries. Computing minimal cut sets (MCSs), i.e., finding all the smallest combination of basic events that result in the top level event, plays a fundamental role in FTA. Classical methods have been proposed based on manipulation of boolean expressions of fault trees and Binary Decision Diagrams...
This paper demonstrates on speeding up an accurate analysis of fault trees using stochastic logic through GPGPUs. Actually, probability models of dynamic gates and new accurate models for different combinations of cold spare gate e.g., two cold spare gates with a share spare and a cold spare gate with more than one spare inputs are developed in this paper. Experimental results show that on average,...

We present a practical, systematical method for the evaluation of the soft error rate (SER) of microelectronic devices. Existing methodologies, practices and tools are integrated in a common approach while highlighting the need for specific data or tools. The showcased method is particularly adapted for evaluating the SER of very complex microelectronic devices by engineers confronted to increasingly...
The dramatic increase in leakage current, coupled with the swell in process variability in nano-scaled CMOS technologies, has become a major issue for future IC design. Moreover, due to the spread of leakage power values, leakage variability cannot be neglected anymore. In this work an accurate analytic estimation and modeling methodology has been developed for logic gates leakage under statistical...
A speed independent circuit has the property that the relative speed of operation of the various logic elements does not affect the over-all behavior of the circuit. Such circuits have properties which are of particular importance in the design of reliable asynchronous circuits. An Arithmetic Control for a digital computer is one type of logic which can profitably use these characteristics. The design...
