This paper presents a systematic method for the
design of a reconfigurable self-healing asynchronous
adder. We propose a graph-based 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 pre-
sented based on this analysis, together with the nec-
essary 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.
