Interactive Mcm-d Layout Editing Software Mcm-editor Development

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.
