A Comprehensive Methodology for Soft Error Rate (SER) Reduction in Clock Distribution Network

Chips
Single Event Transients (SETs) in clock-distribution networks are a major source of soft errors in synchronous systems. We present a practical framework that assesses SET risk early in the design cycle, before layout and parasitics, using a Vulnerability

Contribution to Temporal Fault Tree Analysis without Modularization and Transformation into the State Space

CoRR, 2015
Background: Fault tree analysis (FTA) is a well established method for qualitative as well as probabilistic reliability and safety analysis. As a Boolean model it does not support modelling of dynamic effects like sequence dependencies between fault events.

Integrating Fuzzy Set Theory with Pandora Temporal Fault Trees for Dynamic Failure Analysis of Complex Systems

CoRR
Pandora temporal fault tree, as one notable extension of the fault tree, introduces temporal gates and temporal laws. Pandora Temporal Fault Tree(TFT) enhances the capability of fault trees and enables the modeling of system failure behavior that depends on sequences.

Pandora : a logic for the qualitative analysis of temporal fault trees.

, 2009
Fault Tree Analysis (FTA) is a valuable systems analysis technique widely used in safety analysis and reliability engineering, but it is not without its faults; in particular, it struggles to analyse systems in which time plays an important role, because fault trees use only Boolean logic and so there is no simple way of representing time or sequences ...
