Abstract: Based on PBL (Problem Based Learning)teaching method,it proposed some reforms in the traditional EDA technology course. These reforms are divided into three stages as classroom teaching,basic experiments,and the innovative experiment. During the experiment,we focused on three classes to discuss and solve the problems in the experiment process,and at the same time,we supervise the progress of the experiment. Practice has proved that the reform of the curriculum can greatly enhance students'enthusiasm for learning,stimulate students'curiosity,effectively improve and promote students'self-learning ability,engineering practice ability,teamwork ability and so on.
