Abstract: In the field of electronic information and electronic science and technology, the simulated electronic technology course is the core course for the training of electronic professionals, which is difficult to understand and complicated in circuit analysis. This paper proposes to combine engineering education with the simulated electronic technology course under the framework of OBE and the new engineering background, and adopt virtual simulation software multisim for teaching. It combines project-based learning, promote learning through competition, theory and engineering practice to help students master the knowledge context of analog electronic technology courses and cultivate students'ability to raise and solve problems.

Key words: Analog circuit technology, OBE, Virtual simulation, Multisim, Projectization, Engineering
