| 摘 要： | 介绍了一种量子元胞自动机(QCA)可编程逻辑阵列结构,该结构可用于实现量子元胞自动机大规模可编程逻辑电路,采用QCADesigner仿真软件研究了元胞缺失、移位缺陷和未对准缺陷对可编程逻辑阵列单元逻辑功能的影响。得出了特定结构下,每个元胞移位缺陷和未对准缺陷的最大错位距离,以及导线模式中存在特定位置的8个可缺失元胞。这为缺陷单元的应用提供了一个具体的参数标准,提高了PLA阵列的单元利用率。

| Abstract: | A programmable logic array(PLA) structure that can be used in the large scale integrated circuit using quantum-dot cellular automata(QCA) was introduced.The effects of the cell omission,cell misalignment and cell displacement on the PLA were researched by QCADesigner.And the maximum fault-tolerant ranges of displacement and misalignment for each cell were obtained for a certain structure.Besides that,the 8-cell omission defect in the wire mode was also achieved.The research provides a concrete parameter criterion for applying defect units normally,and advances the utilizing rate of the cell. |
