A QCA Layout Design Methodology. Part I
摘要：
量子点元胞自动机（QCA）作为一种纳米级无晶体管器件技术，在CMOS电路的局限性上具有显着的优势。虽然超过20年的设计进展已经取得了与QCA，一个全面的组成方法，在这项技术的布局设计是必要的。在这项研究中，优先级阶段分解驱动（PPDD）QCA逻辑设计方法的建议。在该方法中，在将组合电路和时序电路划分为包括2：1 MUX和“异”门的初级优先级块和包括多输入择多门的次级优先级块之后，开发了三种流线型方法来使用来自每个优先级的块组成期望的QCA电路。
英文摘要：
Quantum-dot Cellular Automata (QCA) as a nanoscale transistor-less device technology offers distinguishing advantages over the limitations of CMOS circuits. While more than 2 decades of design progress have been achieved with QCA, a comprehensive composition approach for the layout design in this technology is needed. In this study, the Priority-Phased Decomposition-Driven (PPDD) QCA logic design methodology is proposed. In this methodology, after partitioning combinational and sequential circuits into primary-level priority blocks including 2:1 MUX and XOR gates, and secondary-level priority blocks comprising multi-input majority gates, there are three streamlined approaches which are developed to compose the desired QCA circuit using blocks from each priority level.
