The aviation industry has many aircraft in use after more than twenty years of life with some aircraft achieving the fifty years of life milestone. The avionics aboard the older aircraft are based on circuitry elements with diminishing or no manufacturing sources. Entire families of integrated circuits are no longer available, such as the early Intel processors and peripherals, 54C series CMOS logic...
The Prognostic and Health Management (PHM) technology has been widely used as means of improvement for reliability, safety and availability of new generation weapons and commercial products, achieving autonomic logistics. In avionics system, European countries and the USA have been promoting the development, maturing of PHM critical technologies and their applications in military and commercial aircrafts...
Reconfigurable systems are gaining an increasing interest in the domain of safety-critical applications, for example in the space and avionic domains. In fact, the capability of reconfiguring the system during run-time execution and the high computational power of modern Field Programmable Gate Arrays (FPGAs) make these devices suitable for intensive data processing tasks. Moreover, such systems must...
Space applications form a harsh computing environment, especially for sensitive VLSI electronics. Circuits experience both Single Event Upsets (SEUs), as well as permanent failures as a result of incoming electrons, protons, heavy ions, plasmas etc. We propose a Triple Modular Redundancy system that handles transient errors and gracefully degrades the capabilities of the system in the case of a permanent...
In this paper we introduce a fully non intrusive test method which is based on the Differential Electro-Magnetic Analysis (EMA). Our objective is to demonstrate the capability of this new method to detect a modification in a circuit, like a fault voluntary injected would be. This detection is carried out by comparing a reference trace, called Reference Signature, with a differential trace representing...
Systems on Programmable Chips (SoPCs) are receiving an increasing interest from various application domains. Safety critical missions, driven by space and avionics applications, are especially attracted in using SoPCs due to low non-recurring engineering costs, reconfigurability and the large number of logic resources they provide. The capability of partial reconfiguration has recently become a promising...
This paper presents principles and results of dynamic testing of an SRAM-based FPGA using time- resolved fault injection with a pulsed laser. The synchronization setup and experimental procedure are detailed. Fault injection results obtained with a DES crypto-core application implemented on a Xilinx Virtex II are discussed.
Field programmable gate arrays (FPGAs) are getting more and more attractive for military and aerospace applications, among others devices. The usage of non volatile FPGAs, like Flash-based ones, reduces permanent radiation effects but transient faults are still a concern. In this paper we propose a new methodology for effectively measuring the width of radiation-induced transient faults thus allowing...
The purpose of TAFT fault tolerance studies conducted at CNES is to prepare the space community for the significant evolution linked to the usage of COTS components for developing spacecraft supercomputers. CNES has patented the DMT and DT2 fault-tolerant architectures with 'light' features. The development of a DMT/DT2 testbench based on a PowerPC7448 microprocessor from e2v is presented in this...
