Fault detection and diagnosis of safety and mission-critical embedded systems is a constant concern of the aerospace community. There exists a number of fault detection and diagnosis techniques, which are usually based on generating complicated models of the system, or increasing its redundancy. The present paper shows a new approach, based on hash libraries, which allows for fault detection and diagnosis...
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...
Trends show that next coming technologies will produce new generations of very large circuits, running at high clock rates. Some critical applications will have to be protected against the remaining radiation at sea level. This is especially important in aerospace applications because ionizing radiation produces corruption of the internal state. New design methods have to be introduced to assure circuits...
