We describe a method for designing fault tolerant circuits based on an extension of a Concurrent Error Detection (CED) technique. The proposed extension combines parity check codes and duplication in order to not only perform error detection but also provide diagnosis and correction capabilities. Informed selection among the outputs of the original synthesized circuit and the outputs of a constrained-sharing resynthesized duplicate with parity check codes renders a low-cost fault tolerant design. Experimental results con.rm the efficacy of the proposed method as a general solution for designing fault tolerant circuits.
