TFI-FTS: An efficient transient fault injection and fault-tolerant system for asynchronous circuits on FPGA platform

Fault - Tolerant Asynchronous Sequential

A general design technique for achieving single faulttolerant asynchronous sequential circuits is described. The design procedures apply over a large range of fault conditions and are extremely easy to use. Generally, less than three times the logic required for a single copy is needed to achieve single fault tolerance. In addition to fault tolerance, real time fault detection is easily achieve...

FPGA Fault Injection Platform for Secure Device Design Evaluation

In this paper, we describe our current work on developing tools for experimental evaluation of the efficiency of implemented countermeasures against differential fault attacks on cryptographic cores in the FPGA based systems. The developed fault injection platform enables us to analyze the impact of injected faults at the selected points of the FPGA in its run time operation. In its compact ver...

Towards a Systematic Design of Fault-Tolerant Asynchronous Circuits

Accommodating billions of transistors on a single die, VLSI technology has reached a scale where principal physical limitations have a strong impact on design principles. Among the particular challenges are maintaining the synchronous clock abstraction in settings where wiring delays dominate over switching delays, and coping with increasing transient failure rates. In an attempt to address som...

An efficient algorithm for fault-tolerant geocoding

Fault tolerant system with imperfect coverage, reboot and server vacation

This study is concerned with the performance modeling of a fault tolerant system consisting of operating units supported by a combination of warm and cold spares. The on-line as well as warm standby units are subject to failures and are send for the repair to a repair facility having single repairman which is prone to failure. If the failed unit is not detected, the system enters into an unsafe...
