Implementation and analysis of probabilistic methods for gate-level circuit reliability estimation

Implementation and Analysis of Probabilistic Methods for Gate-Level Circuit Reliability Estimation

The development of VLSI technology results in the dramatically improvement of the performance of integrated circuits. However, it brings more challenges to the aspect of reliability. Integrated circuits become more susceptible to soft errors. Therefore, it is imperative to study the reliability of circuits under the soft error. This paper implements three probabilistic methods (two pass, error ...

Evaluating Circuit Reliability Under Probabilistic Gate-Level Fault Models

Circuit reliability is an increasingly important design consideration for modern logic circuits. To this end, our work focuses on the evaluation of circuit reliability under probabilistic gate-level fault models that can capture both soft errors, e.g., radiation-related, and spatially-uniform manufacturing defects. This basic task can, in principle, be used (i) by synthesis procedures to select...

Gate-level power estimation using tagged probabilistic simulation

In this paper we present a probabilistic simulation technique to estimate the power con sumption of a cmos circuit under a general delay model This technique is based on the notion of tagged probability waveforms which model the set of all possible events at the output of each circuit node Tagged waveforms are obtained by partitioning the logic waveform space of a circuit node according to the ...

Gate-level Power Estimation Using Transition Analysis

This paper deals with the problem of estimating the power consumption of CMOS digital circuits, described at gate level. A method is proposed for computing an upper bound on the switching activity of the combinational part of a synchronous circuit. It is based on propagation of abstracted waveform sets, described down to the level of individual transitions. The view of a gate as a relation betw...
