摘　　要：以具有完全自主知识产权的486芯片组为研究对象,将软件工程的需求分析方法引入到芯片组的硬件逻辑设计中,采用自顶向下的模块化设计方法,构造了基于Intel486 CPU的芯片组———OPIAC芯片组的“分层信号流图”,建立了该芯片组的逻辑模型,并构建了一个基于OPIAC芯片组的486主板,以SRAM接口控制为例描述了该芯片组的实现和验证过程。The objection of this paper is to develop 486 chipset with complete Intellectual Property of our own. The method of requirement analysis of software engineering is introduced into the hardware logic design of chipset. A＂Signal Floating Diagram＂ of a certain chipset with complete Intellectual Property, OPIAC chipset, is developed ＇based on Inte1486 CPU, and logic model is built by top- down modularized design method. A 486 main board deploying OPIAC chipset is worked out, and the SDRAM interface is set as an example to describe the process of implementing and verifying the functions of the OPIAC chipset.
