FTUNSHADES2: A novel platform for early evaluation of robustness against SEE

摘要

Large digital integrated circuits designed to solve space applications, have to be designed following standards that recommend to include hardening techniques against Single Event Phenomena caused by harsh radiation environments. It is specifically important in the case of modern deep-submicron technologies. Single Event Effects are phenomena related to the effects of radiation when ionizing particles hit the surface of semiconductors in certain critical areas, where the consequences are mainly data corruption or unexpected behavior with no permanent damage. Fault injection studies are a valuable methodology to evaluate the robustness of the circuit mainly in the early stages of the design. This paper introduces the second generation of the emulation-based fault injection platform FTUNSHADES supported by the European Space Agency, where new features have been included to fulfill with the demands of a growing community of users.
