本文详述了北京理工大学DA实验室开发的从行为功能级描述到结构描述的自动综合系统的设计与实现。该系统接受DDL语言,并通过翻译、数据通路综合、控制部分综合及硬件约束等几个变换过程,生成由器件库中存储的、与实现技术相关的硬件模块组成的结构描述。该系统是采用专家系统设计支持工具OPS5实现的,文中将重点介绍数据通路综合专家系统的实现。
This article details the design and implementation of an automatic synthesis system developed from behavioral functional level description to structure description developed by DA Lab of Beijing Institute of Technology. The system accepts DDL language and generates a structure description of hardware modules stored in the device library and related to implementation technology through several transformation processes such as translation, data path synthesis, control part synthesis and hardware constraint. The system is implemented using OPS5, an expert system design support tool. The article will focus on the implementation of data path synthesis expert system.
