In this paper, we explain the validation of the Cache Analyzer prediction technique thanks to accelerated test experiments. The technique, described in one of our previous works and targeted towards end-user exploitation, focuses on the analysis of cache memory transactions. This paper presents the experimental setup, including the fault detection system used to detect errors in cache memories during the physical validation experiments, and to link them with application failures. We verified that our prediction tool would have correctly predicted the failures. Results obtained during neutron and proton irradiation tests are in accordance with the Cache Analyzer predictions.
