Self Checking Circuit Optimization by means of Fault Injection Analysis: A Case Study on Reed Solomon Decoders

This paper shows how the use of exhaustive fault injection campaigns in conjunction with the analysis of the property of a circuit, allows to improve the efficiency of the checker of self checking circuits. Experimental results coming from fault injection campaigns on a Reed-Solomon decoder demonstrated that by observing the occurred errors and the correspondent detection module has been possible to reduce the number of detection module, while paying a small reduction of the percentage of SEUs that can be detected.
