摘　　要：随着电子信息技术的飞速发展,传统数字电路实验内容虽较为经典,其授课模式难以真实反映学生实验完成情况,难以有效促进学生对理论课程知识的深入理解。对此摒弃传统FPGA黑盒实验系统中的正向验证方式,采取逆向分析方法,通过对电路外特性测试,进行电路功能判断,强化学生数字电路理论知识,提高学生逆向工程、自主设计和工程应用能力。实验设计符合工程教育认证标准,提高数字电路实验教学质量。With the rapid development of electronic information technology,although the traditional digital circuit experiment content is relatively classic,its teaching mode cannot truly reflect the completion of students'experimental tasks,and cannot effectively promote students'in-depth understanding of the knowledge of theoretical courses.The black box experimental system based on FPGA designed in this paper abandons the traditional forward verification method and adopts the reverse analysis method to judge the function through the test of external characteristics of the circuit.The experiment strengthens the students'knowledge of digital circuit theory and improves their ability of reverse engineering,independent design and engineering application.It meets the certification standard of engineering education and improves the teaching quality of digital circuit experiment.
