Survey of Detection, Diagnosis, and Fault Tolerance Methods in FPGAs

FPGAs are important in many different applications, and represent a lot of money in the computer engineering community. They are highly reconfigurable, and thus highly complex. FPGAs must work reliably, and so methods of detection, diagnosis, and fault tolerance have been found to make sure that FPGAs work when they are needed, regardless of present circumstances. Methods of detection include concurrent error detection and roving test. Methods of diagnosis include BIST, application dependent, and partial diagnosis focused methods. Methods for fault tolerance were found that cover single and multi-FPGA systems, as well as for systems experiencing singular faults or multiple faults at once.
