Fault propagation and diagnosis of LUTs in an FPGA without fault free assumptions
T. Nandha Kumar · 2010
This paper proposes a new technique for propagating and diagnosing the faulty LUTs in an FPGA. This technique uses flip-flops and multiplexers for the fault propagation rather than LUTs and therefore the fault free assumption of the LUTs is eliminated. Also this technique diagnosis location of the multiple faulty LUTs precisely thus avoiding any fault masking. This method has been tested on the commercial FPGA and the experimental results are provided.
