The purpose of electronic circuit CAD is to make students master the basic knowledge of computer-aided design of electronic circuits, cultivate their basic ability of electronic system design, combine all functional links with the knowledge of electronic technology system, realize a required function, cultivate students' comprehensive application ability and problem-solving ability, and have the ability to independently design electronic circuit diagrams and plate making. The main task of this project design is to gradually cultivate students' overall system design consciousness by independently using EDA software to design electronic systems, and lay a solid foundation for the analysis and design of complex circuit systems.
