An industrial fault injection platform for soft-error dependability analysis and hardening of complex system-on-a-chip

Abstract

This paper presents a fault injection platform that is currently developed and used to perform soft-error dependability analysis and hardening of complex SoCs. Primarily, it is oriented toward safety analysis, safety requirement conformance testing and hardening of complex SoCs. This platform makes use of clusters of hardware emulation resources available for SoC verification to achieve massive faults injection capabilities. It is able to distribute fault injection campaigns across multiple heterogeneous emulation platforms to achieve high fault coverage. It is able to virtually handle almost any circuit size and is designed to support all kind of designs. We present the first results obtained on a small design, the Leon2 IP, on which exhaustive fault injection have been performed.
