基于九天EDA系统的全定制版图设计

Full-Custom Layout Design Based on the Platform of Zeni EDA System

以反相器等基本单元版图设计为基础,利用华大电子推广的九天EDA系统软件,采用0.6um硅栅CMOS工艺,按照全定制集成电路的后端设计流程,即基本单元建立、版图布局布线以及版图验证对用于数据采集的D触发器进行版图设计。其中着重对数字电路基本逻辑门版图设计技术进行了探讨。此版图已用于相关芯片的设计中,结果表明通过该软件系统设计的D触发器完全符合设计要求。

Zeni EDA Layout software of D flip-flop based on some basic units such as inverter has been designed by using platform of system produced by China Integrated Circuit Design Center, adopting 0.6um Si-gate CMOS process, following a full-custom IC desi flow of back-end, i.e. the construction of basic cell libraries, placement ＆ routing and then layout verification, which is used for data collection unit. Layout design technique about elementary logic gate of digital circuit has been discussed in detail. The layout has been used in an IC. The result shows that design using Zeni EDA software system satisfies design requirement exactly.
