Research On EDA Virtual Laboratory Based On Internet And Virtual Instrument System

Along with the speed development of the Internet technology and the speed expanding of college, various remote education on Internet and virtual laboratory based on Internet appear. This paper puts forward the concept of the virtual laboratory based on Internet, and describes its significance, characteristic developments design theory and method in detail.The system of EDA virtual lab based on Internet applies B/S structure model, it describes the difference between B/S and C/S, and describes the function and advantage of B/S in detail. In the design of application server, it applies the ASP technology and ActiveX technology. Virtual instruments system is the core of the virtual Lab. Firstly, the paper describes the concept, characteristic and development of virtual instruments, based on the analysis of the characteristic and limitation of traditional function oriented design model, the object oriented analysis and design based on UML are introduced and applied. At last, the concrete implementation method and the key technology used are introduced.
