“…In the coarse redundancy approach when a fault is detected in a column, the whole column is marked as faulty and it is then replaced by a spare CLB(configurable logic block) [8], [9]. Scrubbing technique combined with conventional TMR techniques to mitigate SEU effects has been proposed in [10].…”

high reliability is usually the most important requirement in space applications. There is no hardware repair for them. Long mission times and harsh environment are a challenge for electronic circuits, and particular error mitigation techniques have to be implemented in order to be able to cope with the expected error effects. Always, Triple Modular Redundancy (TMR) is relied mostly to prevent SEUs from causing functional errors. And in recent decades, SRAM based FPGAs are used a lot in space for its high performance and flexibility. However, use of FPGAs in space applications can also be challenging. They are too susceptible to transient faults, such as SEUs. Reconfiguration provides more possibilities for SRAM-based FPGAs into space. Reconfigurable technology solves the disadvantage that the TMR modules cannot heal the error themselves. Additionally, reconfiguration is an improvement in terms of resource utilization and costs. In this paper, TMR and reconfigurable computing are combined to level up the reliability of the space applications. The paper proposed a reconfigurable computing architecture based on a TMR system. A new kind of reconfigurable architecture using SoP (system-on-a-package)technology is presented. Also, a whole space application will be presented.

Many techniques have been proposed in the technical literature for repairing FPGAs when affected by permanent faults. Almost all of these works exploit the dynamic reconfiguration capabilities of an FPGA where a subset of the available resources is used as spares for replacing the faulty ones. The choice of the best reconfiguration technique depends on both the required reliability and on the architecture of the chosen FPGA . This paper presents a survey of these techniques and explains how the architectural organization of the FPGA affects the choice of a reconfiguration strategy. Subsequently, a framework is proposed for these techniques by which a fair comparison among them can be assessed and evaluated with respect to reliability. A reliability evaluation is provided for different repair strategies. To provide a comparison between these techniques FPGAs of different size are taken into account. Also the relationship between the area overhead and the overall reliability has been investigated. Considerations about time to repair and feasibility of these techniques are provided. The ultimate goal of this paper is therefore to present a state-of-the-art repair techniques as applicable to FPGA and to establish their performance for reliability.

In this paper, we present a technique to maximize the lifetime of SRAM-based FPGAs in space mission. We focus on recovering permanent faults induced by SEE (single-events effect). In our technique, we use a fix-sized fault detection module to detect permanent faults and propose a permanent fault recovery mechanism for fault recovery. By using partial reconfiguration, we develop a system lifetime estimation model to find the optimal partition for designing the module-based fault recovering with the maximum system lifetime. We conduct experiments with a set of real applications including SpaceWire, Wavelet, AC97, MEPG-4, 8086, and Ethernet on Xilinx XUP platforms. The experimental results show our technique can effectively improve the lifetime compared with the previous work.
