SET fault injection methods in analog circuits: case study
Résumé
Fault injection techniques have been proposed recently to early analyze the dependability characteristics of analog circuits. **The aim of this paper is to compare SPICE level and high level analyses for SET-like faults injections on a PLL mixed analog-digital circuit. Advantages and drawbacks will be discussed, as well as the accuracy of the high level modeling with respect to low level effects of transients due for example to energetic particle hits.
