Reversible logic design is a well-known paradigm in digital computation. In this paper, Quantum-dot Cellular Automata (QCA) is investigated for testable implementations of reversible logic in array systems. C-testability of a 1D array is investigated for multiple cell faults. It has been shown that fault masking is possible in the presence of multiple faults [9]. A technique for achieving C-testability of 1D array is introduced by adding lines for controllability and observability. Rules for choosing lines for controllability and observability are proposed. Examples using the QCA reversible logic gates proposed in [9] are presented.
