This study offers a fully automatic BBN-ANFIS-based model of online condition monitoring system for a resilient MEG using FPGA chips. A direct connection of a FPGA-ZedBoard with on-field sensors is proposed in this study. The design enables real-time concurrent measurements of MEG's fault diagnosis assessment by mean of a hybrid BBN and ANFIS based model. The BBN capable to form a consistent function...
This paper presents implementation of fault emulation method which is very important in today's chip tests on a platform with heterogeneous architecture. Nowadays, the increase in the number of transistors in electronic circuits put fault emulation method forward which is faster than fault simulation in order to obtain a test set against possible defects on chips. In this method, a hardware model...
This work presents a demonstrator for safety-critical applications based on a low-cost FPGA platform. The main goal of the demonstrator is to show the features and benefits of a fault-injection tool for FPGAs called FIJI (Fault Injection Instrumenter) that was developed by the authors of this paper. Besides, the demonstrator should illustrate typical sources of hardware/software faults as well as...
During the last few years, there has been a rise in the use of nanosatellites because they offer a low cost and short development time alternative to larger satellites intended for long-duration missions. The use of commercial components (COTS) instead of the expensive space-grade components required for long missions is one of the main reasons of the popularity of the nanosatellites. This paper presents...
Wire fault detection has been identified as a crucial need for aircraft safety. Several accidents were reportedly caused by intermittent faults such as arcs, encouraging studies on their detection. Detecting intermittent defects is only possible if the detection device is embedded within or close to the harness and it requires a very fast and efficient method, robust to noise. The recently presented...
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...
Some environments (e.g. space, aerospace or medical systems) require electronic systems to withstand an increased, occurrence of faults. Moreover, the failure of these electronic systems can cause high economical losses or endanger human health. Fault tolerance is one of the techniques, the goal of which is to avoid such situations. This paper presents an approach to evaluate the degree of importance...
This paper presents a framework to evaluate the error rate of a design implemented in an FPGA, depending on the operating conditions. The effects of the operating temperature as well as voltage variation are taken into account. For example, in applications such as the electric vehicle motor control, the non-negligible electromagnetic field can result in FPGA supply voltage variation. It is shown that...
Due to the features of FPGA architectures such as high performance and reconfiguration at run time, they have become remarkable contenders for many mission critical applications, much beyond rapid prototyping only. As the feature size of the semiconductor technology shrinks, also FPGA-based systems using underlying nano-technologies suffer from age-induced parameter deterioration that may finally...
Hardware implementations of Object-Tracking Algorithms, like most integrated circuits, are susceptible to radiation-induced soft errors. This work evaluated the reliability of a field-programmable gate array (FPGA) prototype for object-tracking algorithms via fault emulation experiments conducted at the register-transfer level (RTL). Faults were injected into the main sub-modules within the object-tracking...
As the security is becoming more and more important these days, we still should not forget about reliability. When designing a cryptographic device for some mission-critical or another reliability demanding system, we need to make the device not only attack-resistant, but also fault-tolerant. There are many common fault-tolerant digital design techniques, however, it is questionable, how these techniques...
This paper focus on the design of Programmable Logic BIST structures for Very Large Scale Integration (VLSI) Integrated Circuit(IC) testing. The advancements happening in VLSI technology day by day have made chip testing more complicated. This has paved way for the increased popularity of Logic Built In Self Test (LBIST) compared to Automatic Test Equipment (ATE). Logic BIST allows self testing of...
This paper proposes a method for FPGA-based space-borne systems supporting multi-task applications to enable run-time combined adaptation to variations in system power budget and variations in available hardware resources due to occurrence of transient or permanent faults. The adaptation method assumes that each task in the workload has multiple implementations, which can operate at different clock...
The addition of hard blocks such as Block RAMs and Digital Signal Processors, have proven to be good means of improving various performance metrics in FPGAs. This however places stricter constraints on runtime relocation of hardware tasks and hence reduces their application in dealing with permanent faults. In this paper, we present a strategy that enhances the utilization of heterogeneous reconfigurable...
SRAM-Based FPGAs represent a low-cost alternative to ASIC device thanks to their high performance and design flexibility. In particular, for aerospace and avionics application fields, SRAM-based FPGAs are increasingly adopted for their configurability features making them a viable solution for long-time applications. However, these fields are characterized by a radiation environment that makes the...
Mainstream FPGAs and programmable SoCs employ different countermeasures during configuration and runtime to mitigate physical attacks. However, it has been demonstrated that sophisticated active attack techniques, such as laser voltage probing, can still bypass the bitstream protections during the configuration phase. On the other hand, although the security monitoring IP cores provided by FPGA vendors...
The configuration memory of SRAM (Static Random Access Memory) FPGAs (Field Programmable Gate Arrays) is susceptible to SEUs (Single Event Upsets) induced by space radiation, which may result in logic errors and functional disruption of FPGAs. In order to improve the reliability of SRAM FPGAs in aerospace, the SEUs detection and repair of configuration memory are realized by the combination of readback...
Bio-inspired electronic arrays (BIEAs) are circuits that consist of electronic cells. Their self-repairing ability results in high reliability, which brings them many potential demands in aviation field. Recent developments on self-organization and self-repairing methods of BIEA have led to a demand for fault detection as it is the premise of self-repairing. However, the conventional fault detection...
In recent years, SRAM-based FPGAs have been applied in space due to its high density and configurability. However, due to its high sensitivity to SEU, it is difficult to be applied in space. With the decrease of the feature sizes, SRAM-based FPGAs are more sensitive to SEU. Therefore, how to evaluate the sensitivity of a design to SEU in FPGA is very important for the application in space. This paper...
