A methodology for system-level fault injection based on gate-level faulty behavior

In this paper a methodology for creating a high-level faulty models library for simulating low-level fault injection is proposed. The concept of faulty behavior Signature is first proposed in this work. This paper demonstrates how faulty behavior Signatures allow building high level models, for example using Simulink, that reflect with high fidelity the faulty behavior of a combinational circuit represented at gate-level injected with one fault arbitrarily selected from a fault list. It is shown that we are able to capture this behavior with a correlation coefficient of 99.93%.
