| 摘 要： | 针对量子元胞自动机电路中存在的元胞移位、元胞未对准、元胞遗漏、元胞旋转等固有缺陷,采用概率转移矩阵方法建立了一位QCA数值比较器的可靠性模型,并对其可靠性进行了深入分析。对于不同的输入,分别比较了各组成元件在同样的故障概率水平下对整体可靠性(正确输出的概率)的不同影响。仿真结果表明,在所有的输入情况下传输线始终是影响其可靠性的主要因素,从而确定了传输线在该数值比较器中的重要性,进而为大规模QCA数值比较器的设计以及可靠性的提高提供了依据。

| Abstract: | Due to the inherent defects in the QCA circuit,such as the cell displacement,cell misalignment,cell omission,cell rotation and so on,the reliability model of 1-bit QCA comparators was set up through the probabilistic transfer matrix method and its reliability was deeply analyzed.For different inputs,the effect of the individual components on the probability of correct output was compared according to their probability of failure at the same level.The simulation result shows that the wire is the major factor... |
