This paper presents a systematic method for the design of a self-healing asynchronous adder. We propose a graphbased model for the design of a fault-tolerant linear array with external inputs and outputs with a minimum number of spare resources. A K-fault-tolerant asynchronous adder design is presented based on this analysis, together with the necessary support logic for dynamic self-reconfiguration. Experimental evaluations show that our method incurs both low hardware cost and small performance overhead compared to traditional approaches to fault-tolerance.
