Variability in transistor performance will continue to increase with the scaling of technology. Transistors are more and more unreliable. Also, the noise-tolerant capability of circuits is less and less robust. To avoid the loss of yield and fault coverage, the design-for-testability circuit must be designed to be noise-tolerant. This paper presents a soft-error tolerant built-in self-test (SET...

The theory behind fault tolerant multi-level Monte Carlo (FT-MLMC) methods was recently developed and tested. These tests were made without a real fault tolerant implementation. We implemented an MPI-parallelized fault tolerant MLMC version of an existing parallel MLMC code (ALSVID-UQ). It is based on the User Level Failure Mitigation, a fault tolerant extension of MPI. We confirm our FT-MLMC t...

The seven-qubit quantum error-correcting code originally proposed by Steane is one of the best known quantum codes. The Steane code has a desirable property that most basic operations can be performed easily in a fault-tolerant manner. A major obstacle to fault-tolerant quantum computation with the Steane code is fault-tolerant preparation of encoded states, which requires large computational r...

The paper describes an investigation of fault tolerant control strategies for permanent magnet synchronous motor (PMSM) driven by a fault-tolerant inverter. The inverter is a topology-modified inverter with fault-tolerant capability, which can be configured as the standard 3-phase 6-switch inverter and reconfigured as 3-phase 4-switch or 2-phase 4switch inverter under the fault condition. By an...

Today’s integrated circuits are becoming more susceptible to faults due to effects caused by aggressive technology scaling. However, to meet the ever-increasing reliability requirements of safety-related applications, the system has to function correctly even in the presence of faults. This leads to the challenging problem of fault-tolerant system design. Here, the goal is to meet the required ...

The application of robots in critical missions in hazardous environments requires the development of reliable or fault tolerant manipulators. In this paper, we define fault tolerance as the ability to continue the performance of a task after immobilization of a joint due to failure. Initially, no joint limits are considered, in which case we prove the existence of fault tolerant manipulators an...

A new Fault Tolerant Controller (FTC) has been presented in this research by integrating a Fault Detection and Diagnosis (FDD) mechanism in a nonlinear model predictive controller framework. The proposed FDD utilizes a Multi-Sensor Data Fusion (MSDF) methodology to enhance its reliability and estimation accuracy. An augmented state-vector model is developed to incorporate the occurred senso...

In this paper we introduce a new interconnection network Fault Tolerant Hierarchical Interconnection network for parallel Computers denoted by FTH(k, 1).This network has fault tolerant hierarchical structure which overcomes the fault tolerant properties of Extended hypercube(EH).This network has low diameter, constant degree connectivity and low message traffic density in comparisons with other...

Effects of radiation on electronic circuits used in extra-terrestrial applications and radiation prone environments need to be corrected. Since FPGAs offer flexibility, the effects of radiation on them need to be studied and robust methods of fault tolerance need to be devised. In this paper a new fault-tolerant design strategy has been presented. This strategy exploits the relation between cha...
