【摘要】 多芯片组件MCM技术作为一种高密度封装和系统集成的有效手段，近年来得到了日益广泛的应用。开发具有自主知识产权的MCM-D版图编辑工具具有很高的实用价值。本文采用了当今流行的面向对象技术成功地开发出了基于PC机Windows操作系统的交互式MCM-D版图编辑软件MCM-Editor，在国内尚未见有类似的软件系统的报导。 本文的主要内容包括： 1．介绍了MCM及其CAD技术的特点和发展的现状； 2．研究了MCM-D的工艺流程和物理设计的方法，深入探讨了业界标准的版图数据格式——CIF文件的结构和描述版图的风格； 3．建立了MCM-Editor的系统模型。根据面向对象软件工程的观点，遵循事例驱动（Usc case driven）的面向对象系统的开发方法，借助统一建模语言UML和Ration Rose2000面向对象系统建模工具，参照设计模式，建立了MCM-Editor的Use Case模型、交互模型、类模型和组件模型； 4．实现了对MCM-Editor模型的面向对象编程。采用了一种新的缓冲绘图技术来实现MCM-Editor的绘图功能；介绍了MCM-Editor中主要的算法思想，并在Windows98操作系统下，采用Delphi5.0可视化编程语言，完成了软件的编码和调试工作； 5．给出了一个采用MCM-Editor设计出的MCM-D版图的例子，验证了MCM-Editor可基本满足相当于中小规模集成电路的MCM-D版图设计需要。更多还原

【Abstract】 As an effective high density packaging and system integration method, Multi-Chip Module (MCM) technology is applied increasingly in more and more electronic industry fields. MCM-D layout editing software with self intellectual property is doubtlessly of much market value. In the dissertation, a new interactive MCM-D layout editing tool named MCM-Editor based on currently popular Object Oriented (00) technology has been successfully developed in Windows98 operation system. Such contents as following are involved in this dissertation: 1. Characteristic, current developments and trends of MCM and it抯 Computer Aided Design (CAD) technology are systemically introduced. 2. MCM-D抯 general process flow and it抯 physical design method is investigated. Also, grammar structure of California Intermediate Format (Cif) as a standard in electronic industry is studied. 3. MCM-Editor抯 system models in visual diagrams have been created. Directed by Object Oriented Software Engineering (OOSE) methodology, such models as use case model, interactive model, class model and component model have been designed with Unified Modeling Language and Rational Rose2000. As a popular method to develop object oriented systems, the idea of use case driven runs through the whole modeling process. Meanwhile, several design pattern is used for reference in MCM-Editofs class model. 4. With Object Oriented Programming(OOP), MCM-Editor抯 models have been coded and debugged in Delphi5.O and Windows98 operation system. A new buffered drawing technology is used to carry out MCM-Editor抯 drawing function. Main arithmetic ideas in the software are described in details too. 5. Finally, a MCM-D layout example designed with MCM-Editor is provided, which validates that MCM-Editor can meet the requirement of general MCM-D抯 layout editing.更多还原
