Three core modules are developed as design and mask pattern verification module,database module, and device characteristics simulation module. All the operations are controlled under Microsoft Windows GUI interface. This leads to a reduced design and fabrication cycle, workload and cost. With the knowledge-based library for intelligent design and Lotus Notes database for distributed and networked engineering database management (EDM) and effective control of documents, a new enterprise-leveled, computer-integrated design and manufacturing system (CIDMS)can be established for monolithic and hybrid device design (not only confined to SAW device).展开更多

From the viewpoint of software architecture, this paper first presents TBus architectural style, which is a kind of CASE environment architectural style based on ToolBus, then describes the architectural model and system's behavior in formal method, researches and analyzes the corresponding tool structural model.
