Concurrent detection of transient faults in microprocessors
… in digital systems are due to the presence of transient faults. This is especially true of microprocessor-based systems working in a radiation environment that experience transient faults due to single event upsets. These upsets cause a temporary change in the state of the system without any …

Recovery from transient faults in wavefront processor arrays
A transient fault in an array of processing elements results in an inconsistent or incorrect state in the processing element. If the erroneous information has already propagated before detection occurs, then the neighboring processing elements can also be in an incorrect state. Restarting the …

A gate-level simulator for alpha-particle-induced transient faults
… available for accurate alpha-particle-induced transient fault simulation. However, they are not fast enough to simulate a large number of transient faults on a relatively large circuit in a reasonable amount of time. This thesis describes a fast transient fault simulator which can evaluate the …

High level strategy for detection of transient faults in computer systems
… are due to the presence of temporary faults which are either intermittent or transient. An intermittent fault manifests itself at regular intervals, while a transient fault causes a temporary change in the state of the system without damaging any of the components. Transient faults are …

Simulation of faults causing analog behavior in digital circuits
… simulation methods for electrically oriented faults in digital metal-oxide semiconductor (MOS) very large scale integrated (VLSI) circuits. In particular, we are interested in the simulation of permanent electrical faults that are difficult to model using a logic-level or switch-level …

Probability of latching single event upset errors in VLSI circuits
The ability of radiation to cause transient faults in space borne as well as ground based computers is well known. with the density of VLSI circuits increasing every year, the probability of an upset by radiation is becoming more likely. However, research in this area has matured over the last …

A fault tolerant bus interface unit based on the nubus standardized bus architecture
… Satellite-based systems are susceptible to transient faults caused by cosmic radiation or alpha particles. In order for a system to be usable in such an environment, it must be designed to be upset tolerant. Functionality of the design must be intact in the presence of transient faults. …

Transient fault detection using a watchdog processor
… period but leave no permanent damage. These transient faults are difficult to predict, prevent, or detect but can lead to a system failure if not discovered.

Susceptibility evaluation of combinational logic in VLSI circuits
… radiation environment. These errors are due to transient faults which may cause a temporary change in the state of the system without any permanent damage. These transient faults are referred to as Single Event Upsets (SEUs). Because of their random and non-recurring nature, such faults are very …

Self-stabilizing wormhole routing
… is a technique that guarantees tolerance to transient faults (e.g. memory corruption or communication hazard) for a given protocol. Transient faults would typically place the network in an illegitimate state, while Self-stabilization guarantees that the network recovers a correct behavior in …

The design of periodically self restoring redundant systems
… systems can be designed to be tolerant of both transient (intermittent) and permanent hardware faults. Further, the reliability of such designs is not compromised by fault latency. The periodically self restoring redundant (PSRR) systems presented in this dissertation employ, in general, N …

An investigation into 88 KV surge arrester failures in the Eskom east grid traction network
… are different. It is suspected that fast transient faults in this network initiate system faults leading to surge arrester design parameter exceedances and poor network insulation coordination. Preliminary investigations in network suggest that transient studies were not done during …

Dynamic investigation of vibratory screen response in a FEM environment
… are crucial in the understanding of faults and failures which occur in vibratory screens. However, the current available models are usually simplified and have limited validation to that of a physical screen. Much research has been conducted to optimise the screening efficiency of …

On fault tolerance of hardware samplers
… the robustness of hardware samplers to hardware faults. This study was motivated by our observation that several applications use sampling as a primitive and that sampling itself is an approximate method for computation. As such, it might be possible to lower energy consumption of hardware …

Detecting and Recovering from In-Core Hardware Faults Through Software Anomaly Treatment
… solution that effectively handles hardware faults while incurring low cost during the common mode of fault-free operations. SWAT is based on two key observations about the design of resilient systems. First, only those hardware faults that affect software need to be handled and second, since …

Self-stabilizing sorting algorithms
… machine gets a partial view of the global state. Transient failures in one area of the network may go unnoticed in other areas and may cause the system to go to an illegal global state. However, if the system were self-stabilizing, it would be guaranteed that regardless of the current state, the …

Study of Single Event Transient Error Mitigation
Single Event Transient (SET) errors in ground-level electronic devices are a growing concern in the radiation hardening field. However, effective SET mitigation technologies which satisfy ground-level demands such as generic, flexible, efficient, and fast, are limited. The classic Triple Modular …
