摘　　要：在目前课程学时逐渐减少,教学培养要求却不断提高的情况下,分析了数字电路课程的基础内容与教学目标,在不增加学时的同时,丰富了实验内容,提高学时的利用效率,在积极开展课程设计的要求等背景下设计、研制了数字电路教学实验平台。在教学平台中设计了常规芯片的验证与演示模块,减少器件损耗;为了方便并行数字信号的实验,设计了8位二进制数字信号单元。其他具有特色的功能还包括:三态逻辑笔功能单元、FPGA可编程单元、单脉冲发生单元、DAC、ADC单元、液晶显示单元等。平台的设计是在已用的平台改进而来的,对基础课程教学和初学者提供了方便。In view of the current curriculum time gradually reduced and the teaching requirements continue to improve,summarized and analyzed the basic contents and teaching objectives of the digital circuit curriculum.A digital circuit teaching experimental platform was designed and developed in the absence of additional course hours and enriching the experimental content,improve the efficiency of course hours,at the same time actively carry out the curriculum design.In order to reduce the device loss,a conventional chip verification and demonstration module was developed.In order to improve the understanding of digital signal,a 8-bit binary digital signal unit was designed.Some other features include: tri-state logic pen unit,FPGA programmable unit,single pulse generating unit,DAC,ADC unit,liquid crystal display unit etc.The design of the platform is improved from the already used platform,which has provided a convenient and basic value for the basic course teaching.
