Flash-based FPGAs are increasingly demanded in safety critical fields, in particular space and avionic ones, due to their non-volatile configuration memory. Although they are almost immune to permanent loss of the configuration data, they are composed of floating gate based switches that can suffer transient effects if hit by high energetic particles with critical consequences on the implemented logic. This paper presents a new way for the analysis of the impact of Single Event Effects in Flash-based FPGAs. The authors proposed a new methodology to identify the most critical switches inside the configuration logic block and the most redundant and robust configuration selection for each logic function.
