中文摘要：

针对目前高校电工电子实验教学中存在的问题，该文从提高学生实践动手能力出发，在电工电子实验课程中引入可编程逻辑器件。把传统电子电路设计与FPGA设计做了比较，锻炼了学生基于模块化设计数字电路的能力以及调测复杂电路的水平。将组合逻辑和时序逻辑结合，通过VHDL语言设计动态显示典型案例，该案例可以作为其他单元电路设计的模板，突出了基于硬件描述语言设计硬件电路的灵活性。实践表明，案例教学法作为一种交互式的教学方法，增强了学生学习的兴趣，使学生主动参与学习，提高了学生对实际工程的认知能力和解决问题的综合能力。

英文摘要：

Focus on the problems existing in the electrical and electronic experimental teaching in colleges and universities, in or- der to improve students＇ practice ability, this paper introduces the programmable logic devices in electrical and electronic experimental course. The traditional electronic circuit design is compared with FPGA design, thus it exercises the students＇ ability of designing digital circuit based on modular, and the debugging level for complex circuits. Combing the combinatorial logic with temporal logic, we design a typical case with the dynamic display using VHDL language. This case can be used as a template for other unit circuit design, and highlights the flexibility of designing a hardware circuit based on a hardware description language. Practice shows that the case teaching method, as an interactive teaching method, enhances students＇ interest in learning and makes students take part in learning actively and improve students＇ comprehensive ability of cognition and solving problems.
