With the continuous progress of modern information technology and the continuous reform of teaching methods, practice has become an important link for students to deeply understand theoretical knowledge. Experiment has become an indispensable part of teaching and the most effective means to improve students' creativity and practical ability. The phenomenon of electronic courses is often invisible and intangible. According to the electrical characteristics of electronic courses, virtual simulation technology is adopted to simulate the electrical characteristics of electronic courses in the classroom teaching process. Through the simulation of electronic circuit laws, promote the integration of classroom teaching theory and practice. Introducing virtual simulation technology into electronic experimental teaching is the direction of experimental teaching development. The concept and advantages of virtual simulation technology are explained, and the application of virtual simulation technology in experimental courses is introduced. Virtual simulation technology has the characteristics of openness and flexibility, which can organically combine theory and practice, greatly improve the efficiency and effect of experiments, and is the direction of experimental teaching reform and development.
