摘 要 进入21世纪以来，我国信息产业在生产和科研方面都大大加快了发展速度，并已成为国民经济发展的支柱产业之一。但是，与世界上其他信息产业发达的国家相比，我过在技术开发、教育培训等方面都还存在这较大的差距。集成电路已经发展到了系统级芯片（SOC）的阶段。随着CMOS 工艺阶段的进步，由于CMOS电路的低成本，低功耗、以及速度的不断提高，由于CMOS模拟电路设计的技术不断进步，CMOS技术已被证明是实现SOC的最好选择。模拟电路是SOC中不可缺少的部分。由于器件尺寸不不断缩小和低电源电压，低功耗等要求，模拟CMOS集成电路设计在不断的发展，在SOC中变得越来越重要。作为设计与制造的纽带，版图的地位至关重要。在各类集成电路中，模拟集成电路由于对器件的依赖性更强，所以起性能更大程度上受到版图因素的影响。 关键字：集成电路设计，版图设计 ABSTRACT Since the 21st century, Chinas information industry in production and research aspects are much faster development speed, and has become a pillar industry of the national economy development. However, with the world of information industry developed countries other than, I live in technical development, education training etc are still exist in the larger gap Integrated circuit has developed into system level chip (SOC) stage. Along with the progress of stage of CMOS technology, due to the low cost, CMOS circuit, and low consumption rate rise ceaselessly, because the CMOS analog circuit design technology progress, CMOS technology has been proved to be the best choice of SOC realization. Analog circuit is an indispensable part of SOC. Due to the device size and low voltage shrinking, low power consumption, analog CMOS integrated circuit design in the unceasing development, in the SOC of becomes more and more important. As the design and manufacture of the link, the position is very important. In all kinds of integrated circuits, analog circuits due to the dependence of the device, so its stronger performance greater extent by the factors which influence the territory. Key Words: integrated circuit design, layout design目 录 第1章 引言 1 1.1 选题背景 1 1.2 研究目标和意义 1 1.3 研究思路 1 第2 章 版图设计理论基础 2 2.1版图概念 2 2.2 版图设计过程 2 2.3 版图验证与检查： 3 2.4 版图设计注意事项 3 第 3 章 Cadence 工具使用 5 3.1 Cadence 软件简介 5 3.2. 建立新库和新文件 6 3.3 版图的验证 8 3.4 布局相关 11 第 4 章 模拟版图设计匹配 13 4.1 匹配的概述 13 4.2模拟电路版图设计中的匹配艺术 13 4.2.1 根器件法(Root Device Method) 13 4.2.2 交叉法(Interdigitating Devices) 14 4.2.3 虚拟器件法 14 4.2.4 共心法(Common Centroid) 15 4.2.5 匹配信号路径
