In this paper, starting from the whole process of higher education personnel training, aiming at cultivating students with engineering innovation ability required by enterprises, a comprehensive and systematic practice platform is constructed. The platform adopts the stages, continuity, practice mode, build mutual connection, the overall unity of practice teaching system, so that students in different learning stage to complete each independent unit of the circuit design, can blend in unit circuit in the system, and each stage of the unit can be design together, constitute a fully functional comprehensive experiments. At the same time, all kinds of pre-competition training will penetrate into all stages of undergraduate teaching to maximize the benefits of competitive learning mechanism.
