Abstract: Analog electronic technology experiment is the basic experimental course for electrical majors, which plays a pivotal role in strengthening students'theoretical knowledge and improving their engineering practical ability. Aiming at the problem of poor teaching effect of traditional analog and electric experimental courses, an experiment teaching reform of analog electronic technique integrating virtual and reality is proposed, which based on Analog Discovery Studio (ADS) platform and the integration of Multisim simulation, PCB design, soldering and testing. Taking the experiment of sawtooth wave generation circuit as an example, the teaching content and steps of this analog electronics experimental teaching reform are introduced. As the experimental teaching content basically includes the whole process of electronic product design, it is easier to stimulate students'learning interest. Teaching practice shows that students obtain a higher sense of achievement after completing the experiment, the subjective initiative to do experiments is greatly strengthened, the students'engineering thinking and engineering practice ability is cultivated, and the effect of experimental teaching has been significantly improved.

Key words: Analog Discovery Studio, Analog electronics experiment, Multisim simulation, Sawtooth wave generation circuit, Curriculum reform, Virtual-reality integration
