Resumo da Palestra
It is well known that the permanent progress of integrated circuits manufacturing processes has a negative impact on the reliability of systems built from advanced circuits. The phenomena so-called Single Event Effect (SEE) gathers the different types of consequences resulting from the impact of a single energetic particle with a sensitive zone of a circuit.
Since 1993 the results of many “real-life” experiments (in balloons, aircrafts and high mountains) were published in the scientific literature. These experiments provided an objective feedback about the faults occurring in circuits including large sensitive areas, such as memories and Field Programmable Gate Arrays (FPGA), operating at different altitudes and allow validating solutions to guarantee the required dependability of targeted applications. Such experiments required huge numbers of parts because of the relatively low neutron flux (even at avionic altitudes) and the low sensitivity to SEUs of the used process technologies. Presently available technologies would allow designing real-life experiments with significantly lower number of parts and power consumption.
The researchers of the preceding STIC-AMSUD project (HARMLESS project) allowed to collected results concerning the effects of natural radiation on integrated circuits in different locations at high altitude in France, Peru and Argentina.
Factometrics project aims at comparing these results with accelerated irradiation experiments using test platforms already developed and validated at TIMA labs with irradiation facilities in Argentina and Brazil.
Another important goal of Factometrics project is the confrontation of experimental results in accelerated conditions and those issued from real environment during the high altitude test campaigns including ground and flight measurements, to those predicted by state-of-the-art tools, such as MUSCA SEP3 developed by ONERA DESP. This will allow improving the knowledge of the impact on up-to-date technologies and validate experimental techniques to accurately forecast.
