This work investigates techniques for building fault-tolerant digital circuits at the nano-scale. It provides an overview of some nano-scale technology candidates that can be used in the next generation of digital circuit based on nanoelectronic logic fabrics. It focuses on fault tolerance of such circuits at both the circuit and the architecture level. A case study based on pass-transistor logic using wrap-gate nanowire devices is presented. Such circuits implement logic computing in the form

In addition, a planarization algorithm is presented and implemented in order to synthesize planar error correcting circuits using such devices. Alternative architecture, such as the cross-bar nano-FPGA, is considered as another candidate for fault-tolerance. Simulation and modeling of all the presented architectures are performed using the developed software "BDD processing tool", CUDD package and SPICE.
