Reliability Modeling of Large Fault-Tolerant Systems

A cluster based ultra reliable architecture is pre sented o ering synchronization and system function ality comparable to that of fully connected systems with reduced system overheads Existing combina torial and Markov models do not su ciently model concurrently occurring faults in such large systems A reliability model considering the distribution of con current faults across the system cluste...

Reliability Monitoring of Fault Tolerant Control Systems

This paper proposes a reliability monitoring scheme for active fault tolerant control systems using a stochastic modeling method. The reliability index is defined based on system dynamical responses and a safety region; the plant and controller are assumed to have a multiple regime model structure; and a semi-Markov model is built for reliability evaluation based on safety behavior of each regi...

Restoring Reliability in Fault Tolerant Reconfigurable Systems

The new generations of SRAM-based FPGA devices, built on nanometer technology, are the preferred choice for the implementation of reconfigurable computing platforms. However, smaller technological scales increase their vulnerability to manufacturing imperfections and hence to the occurrence of electromigration. Moreover, the large internal RAM (for configuration purposes or as embedded memory b...

Reliability Analysis of Fault Tolerant Systems with Multi- Fault Coverage

Fault-tolerance has been an essential architectural attribute for achieving high reliability in many critical applications of digital systems. Automatic fault and error handling mechanisms play a crucial role in implementing fault tolerance because an uncovered (undetected) fault may lead to a system or a subsystem failure even when adequate redundancy exists. Examples of this effect can be fou...
