Abstract
Reversible logic design is a well-known paradigm in digital computation. In this paper, Quantum-dot Cellular Automata (QCA) is investigated for testable implemementations of reversible logic in arrays systems. C-testabilityof a 1D array is investigated for multuple cell faults. It has been shown that faults masking is possible in the presence of multiple faults. 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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
