New Insights Into the Single Event Transient Propagation Through Static and TSPC Logic

Abstract

An investigation of the Single Event Transient (SET) characteristics (amplitude and width) variation while propagating through static and True Single Phase Clock (TSPC) logic is presented. The dependencies of the SET characteristics on the input patterns, propagation paths, pulse polarity, diverging paths, and re-converging paths are investigated. New insights on the propagation induced pulse broadening (PIPB) phenomenon in different combinations of static and TSPC logic are reported. The worst and the best propagation paths for SET pulse broadening and attenuation are identified. Our results demonstrate that SET pulses propagation can lead to Byzantine faults as they propagate through diverging paths. A new way to abstract all possible interpretations of the SET induced Byzantine fault phenomenon is proposed.
