In order to further adapt to the current training needs of digital circuit engineering talents, a new experimental teaching system has been explored and tried.Four aspects are explored, which are experiment content, teaching method, selfmade equipment and evaluation system.A hierarchical and progressive experimental content system is designed, and the flipping classroom and microcourse are combined.The experimental equipment is designed to support the offline experimental teaching.The process assessment is emphasized to fully mobilize the initiative of learning.Two years’ teaching practice proved that this teaching system has achieved initial goals.
