Abstract

One of the current trends in space electronics is towards considering the adoption of COTS components, mainly to widen the spectrum of available products. When substituting space-qualified components with COTS ones a major challenge lies in guaranteeing the same level of reliability. To achieve this goal, a mix of different solutions can be considered, including effective test techniques, able to guarantee a high level of permanent fault coverage while matching several constraints in terms of system accessibility and hardware complexity. In this paper, we describe an approach based on Software-based Self-test, which is currently being adopted within the MaMMoTH-Up project, targeting the development of an innovative COTS-based system to be used on the Ariane5 launcher. The approach aims at testing the OR1200 processor adopted in the system, combined with new and effective techniques for identifying the safe faults. Results also include a comparison between functional and structural test approaches.
