| The prosperity and development of modern education especially distance education, needs a more extensive application of distance experiment education. Consequently, it has become an emphasis in many universities and institutes.Among numerous kinds of experiments, the Analogy/Digital Electronics Experiment is one of most basic course. It acts just like a bridge which connects theoretical knowledge and practices. The experiment is the essential factor of the course, through which the students will be trained to acquire the ability of design and test in circuit construction.SPICE, which is most popular circuit simulation software, plays an important role in this course. It provides students a virtual platform on which parts and instruments are presented. In the case of equipments shortage, it is a good solution.However, SPICE is a program which runs in a non-network environment so that users cannot share the resource, and its complexity makes it difficult for users to master. At the same time, the platform of SPICE cannot present a vivid environment for users.The thesis introduces a new implementation of virtual laboratory which combines simulation, networking and multimedia. The content includes the process of mutual in client-side and server-side, inputting interface of simulation program (.cir), output data analysis and creating code model.Especially, the paper presents a solution to simulation of sequential circuit, which consists of continuance-segment simulation model. |
