| 摘 要： | IC设计数据管理是研制一体化IC-CAD系统的重要内容。本文提出了一个适于CAD设计数据管理的语义数据模型及在此模型下IC设计数据的具体表示及管理。语义数据模型提供了表达设计实体及其相互依赖关系的一体化方法。基于此模型的设计数据管理软件已在Unix Sun3工作站上构成,并成功地应用于组合电路逻辑综合系统中。语义数据模型能提高CAD系统的可扩充性,并可很好地支持系统的模块化结构。

| Abstract: | The management of IC design data is an important aspect in the development of an integrated IC CAD system. In this paper, a semantic data model for the management of IC CAD data is proposed, and the specific representations and management of the data in the model are given. By the semantic data model, an integration method to express design entities and their interdependence is provided. A software for design data management based on this model has been developed in Unix Sun 3 and applied successfully to an integrating system for circuit combination logic. Using this semantic data model, improved extendability of a CAD system and good support of the modular structure of the system can be achieved. |
