In Response to the existing problems with the traditional electronic circuit teaching, a solution which uses the EDA simulation software is proposed. AS some teaching examples, this paper illustrates how to use EDA simulation software in the Digital electronic technology curriculum classroom instruction, the curriculum project and graduation project. It also points out the introduction of EDA simulation software into electronic circuit Course, facilitates teaching and arouses Student's interests in the course of simulating and demonstrating, and helps eliminate student's abstractness of theory while strengthening student's perceptual knowledge. The introduction of EDA simulation software into electronic circuit course intrigues the sound, simultaneous interaction between teaching and learning and facilitates students' understanding of fundamental logic circuit theory as well as its wide application.
