基于网表的量子元胞自动机时钟布局方案

QCA clock layout based on traditional netlist

量子细胞自动机(quantum cellular automaton,QCA)器件是一种具有时控工作特征的新型器件结构,与传统的通过电信号来表示二进制信息的方法不同,它是通过电子在QCA 细胞上占据的位置来表示的。正是由于QCA器件的时控工作特征,若没有一个系统合理的方法设计QCA时钟电路,则会导致电路时钟设计复杂、电路时钟周期冗余。文章基于传统集成电路成熟的网表技术,引入了新的网表参数,使得在进行电路器件设计时也能解决时钟布局的设计,缩短了电路设计时间、提高了时钟的合理布局。

Quantum cellular automaton(QCA) is a new device structure with time control characteristics. It is different from the traditional way to represent binary information through electrical signals. It is represented by the position of electrons on QCA cells. Because of the time control characteristics of QCA devices, if there is not a systematic and reasonable way to design QCA clock circuit, it will lead to the complexity of circuit clock design and the redundancy of circuit clock period. Based on the mature netlist technology of traditional integrated circuits, the new netlist parameters are introduced. When designing circuit components, it can also solve the design of clock layout, shorten the time of circuit design, and improve the rational layout of clock.
