A fault-tolerant technique to detect and recover from open faults in FPGA interconnects

Abstract

Nowadays, FPGAs play a great role in electronic circuits design especially in implementing critical applications. As a result, the need for adding fault-tolerance to FPGAs becomes very important. In this paper, a fault-tolerant technique and associated modifications on FPGA architecture are proposed. This technique can detect and recover from open faults in programmable interconnects. It was successfully simulated using an FPGA-based simulator.
