Radiation Testing of Electronics Systems: How Can Simulation Tools Help in the Definition and Optimization of Test Plans in Labs?

International audienceOn-board space systems are exposed to harsh environmental conditions includingradiations, extreme temperatures and high-vacuum… Each component of thisspace environment, either separately or in synergy, induces short or long termdegradation of electronics or materials, thereby impacting reliability. The wide diversityof observed disruptions, potential anomalies (and therefore of their underlyingphysical-chemical mechanisms) and the large set of technologies involved requirethe development of modeling tools to support experimentation, in order to achieve arepresentative simulation of device response and a reliable prediction of the life, as wellas to limit ground testing
