新型可编程“黑盒”数字功能元件设计

Design of a New Programmable"Black-box"Digital Component

针对“电子线路实验I”不能真实反映学生实验任务完成情况、无法有效考核学生对实验知识点掌握程度,以及不能促进学生对理论课程知识点加深理解等问题,该文研究设计一种新型的可编程“黑盒”数字功能元件。该可编程“黑盒”数字功能元件可以根据实验任务要求和考核知识点,以及不同学生往期实验任务完成情况,动态生成功能多样、引脚布局定义各异的数字功能元件。通过使用该“黑盒”数字功能元件设计搭建相关的数字逻辑电路,可以真实反映学生实验任务的完成情况,有效考核学生对实验考核知识点的掌握程度,准确考查学生的实验水平与实践能力,并达到巩固理论课程相关基础知识,培养学生的基本实验技能和工程素质的实验教学目标。

Aiming to accurately assess the students'performance in Experiment in Electronic Circuits I,and to expand the students'understanding of the knowledge taught in related theoretical courses,a new programmable black-box digital component is designed in this paper.The function and the pin definition of the proposed programmable black-box digital component will be dynamically changed with the purpose and claims of the experiment task,as well as the past performance of each student.After building a required digital functional circuit with the programmable black-box component,the performance of each student will be accurately examined,and the target of expanding the students'understanding of the knowledge,as well as developing the students'basic experimental skills will be achieved finally.
