【Abstract】 The article offers a kind of means for schematic comparison. The method is to define the characteristic vector for a circuit diagram,and then to convert information of a two-dimension circuit diagram into one-dimension character information. By extracting and comparing characteristic vector of circuit diagram,two circuit diagrams are judged whether or not to be consistent with each other. The method proposed in this paper can be applied to the development of analog circuit design practice system,and realized the automatic evaluation on right or wrong for circuit design.Application results show that the method is simple and effective,the practice system is highly regarded,and has high application value and promotion prospects.更多还原
