摘　　要：围绕电子信息技术专业人才的培养,以学生工程能力培养为目标,提出数字电子技术基础课程实验教学的改革思路。兼顾传统实验项目的同时,在课程设计的设置中向由FPGA芯片到系统设计延伸,培养学生的系统观念和软、硬件一体化设计能力。在序列信号发生器自启动特性验证实验设计中,设计了不能自启动、慢速自启动、中速自启动和快速自启动等4种方案,比较几种自启动方案的自启动时间,强调多实现方案中的优化方案选择,引导学生关注实际工程问题。设计的FPGA实验电路板,能够保存4个不同的配置文件,可不再依赖计算机完成4个设计文件的重配置,该实验电路板可作为口袋实验室,用于学生课下自主学习,提升学生的实践能力和创新意识,为以后面对复杂工程问题解决能力的培养起积极作用。Aiming at cultivating students'engineering ability of electronic information technology specialty,reform idea of digital fundamental experimental teaching is proposed.In addition to taking into account the traditional experimental project,it is emphasized to do design from signal chip to the system in the curriculum,which can develop students'system concept and software and hardware integrated design ability.In the experimental design of self-startup characteristic verification of the sequence signal generator,four schemes,i.e.,non-self-starting,slow self-starting,medium speed self-starting and fast self-starting,are designed to compare the self-starting time of different schemes.The optimization in the multi-implementation scheme is emphasized,which guides students to pay more attention to the actual engineering problems.The designed FPGA experimental circuit board can save four different configuration files,and the storage is no longer to rely on the computer,it can be used as pocket laboratory for students in autonomous learning,which can enhance students'practical ability and innovative consciousness to solve complex engineering problems after graduation.
