Abstract: This paper proposes a reform pattern of progressive experimental teaching of digital circuit.The electronics design automation(EDA)software Multisim12.0 and experiment boxes based on programmable system on chip(PSoC3)are applied to digital circuit experimental teaching.The digital circuit experiment teaching can be divided into three stages,which was based on the “components” and Multisim12.0 simulation verification experiments,design experiments based on Multisim12.0 or PSoC3,and comprehensive experiments based on PSoC3.The proposed reform pattern can not only help the students master the theory of digital circuit,but also improve their ability of practice and innovation.
