Reliability Properties Assessment at System Level: A Co-design Framework

This paper introduces an enhanced hardware/software co-design framework allowing the designer to introduce hardware fault detection properties in the system under consideration. By considering reliability requirements at system level, within a hw/sw co-design flow, it is possible to evaluate overheads and benefits of different solutions. System specification, hardware and software concurrent fault detection design methodologies and hw/sw partitioning are the three key factors taken into account. The paper discusses these aspects providing a complete overview of the reliability co-design project.
