Journal ArticleDOI
A survey of fault tolerant methodologies for FPGAs
TL;DR: This survey attempts to provide an overview of the current state of the art for fault tolerance in FPGAs, assuming that faults have been previously detected and diagnosed and the methods presented are targeted towards tolerating the faults.
Proceedings ArticleDOI
An FFT approximation technique suitable for on-chip generation and analysis of sinusoidal signals
TL;DR: This paper presents an FFT approximation technique suitable for on-chip spectral BIST signal generation and analysis and shows that the noise produced by the approximation technique is under 24.74 dB for a 256 point FFT with a 32 point approximate kernel.
Proceedings ArticleDOI
On-line incremental routing for interconnect fault tolerance in FPGAs minus the router
John M. Emmert,J.A. Cheatham +1 more
TL;DR: A Fault Tolerant technique for programmable interconnect on Field Programmable Gate Arrays (FPGAs) that does not require a router at the time FT reconfiguration is performed and generates precompiled FT partial configurations that can be downloaded when faults occur.
Book ChapterDOI
Performance Penalty for Fault Tolerance in Roving STARs
John M. Emmert,Charles E. Stroud,J.A. Cheatham,Andrew M. Taylor,Pankaj Kataria,Miron Abramovici +5 more
TL;DR: This paper analyze the performance penalty of a fault-tolerant (FT) adaptive computing system (ACS) that implements the roving Self Testing AReas (STARs) approach for on-line testing and fault tolerance for FPGAs and presents a procedure for estimating the worst case performance penalty.
Proceedings ArticleDOI
A monolithic spectral BIST technique for control or test of analog or mixed-signal circuits
TL;DR: This paper outlines a spectral based, mixed-signal approach for monitoring the health of analog and RF components in mixed-Signal systems on-chip, and reduces required hardware by using the same functional block to analyze analog output signals that are used to generate m tone stimulus signals.
