Simulation on Experiment of Automatic Principle Based on OrCAD/PSpice

s: The flaw of the traditional experiment and the present situation of the simulation experiment were introduced. The simulation function was analyzed that EDA was used in the experiment of automatic principle in detail. According to the example of Second Order, the way was elaborated that how OrCAD/PSpice used simulation of combination in the experiment of Step Leap Response and how OrCAD/PSpice used simulation of parameter in the experiment of frequency characteristic. The results of the experiment prove that this method has hardly any error and works well and efficiently. It can arouse students, enthusiasm in doing experiments and also solve the problem of lacking of instrument when there are so many students.
