EDA Virtual Lab Based On Internet

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.The paper mainly discusses EDA long range virtual laboratory system based on internet. The system is composed of circuit edit, virtual instrument display, circuit simulation and circuit optimization. The paper provides OOD method which be used to construct the system to simplify complexity and enhance reusability. The design center algorithm for circuit design has been studied thoroughly. An optimal algorithm and theory to Design Center Problem is proposed. This paper realized the electric circuit center value optimization through to a kind of algorithm application.
