基于量子元胞自动机容错反相器的设计

Design of Fault-Tolerant Inverters Based on Quantum Cellular Automatas

分析了由线、反相器、扇出、择多逻辑门等量子元胞自动机组成的基本电路在工艺制造过程中可能存在的故障,基于块择多逻辑门的冗余结构设计思想,设计出具有容错能力的量子元胞自动机反相器,最后利用QCADesigner软件对位于不同输入输出点的极化值进行了仿真研究和验证。结果表明,所设计的反相器结构对称,输入与输出方式多样性,对元胞位移故障和元胞缺陷故障具有较好的容错能力,这将对构成更复杂的大规模QCA集成电路容错的研究具有一定的借鉴意义。

Faults in the process of basic circuits constitued by the wire, inveter, fanout, majority voter gates of the quantum cellular automata （QCA） were analyzed. Based on the idea of redun- dancy design of block majority voter gates, the inverter based on the quantum cellular automata with the fault tolerance was designed. The polarization values of different in-out dots were simu- lated and verified by QCADesigner. The results show that the designed inverter has the characteristics of the symmetry, diversity of in-out mode, good fault tolerance to the cell displacement fault and the cell omission fault, which is of great significance for the study of fault tolerance in the more complicated large-scale integrated circuits of QCAs.
