摘要
将VHDL硬件描述语言对EPM71288LC84-10型CPLD芯片编程结合到试验台中,达到自动检测学生所连接的车灯电路系统各接点的接线是否正确,用数码显示器显示错误接线位置并根据其接线情况自动进行打分。该系统能取代老师逐个检查、解决线路繁琐和浪费时间的问题。此系统简单易行,造价较低,根据不同的试验台可编辑不同的程序,可广泛应用于学生实验设备中。
The design in this paper conducted programming on EPM71288LC84-10 CPLD chip by VHDL hardware description language.Through combining it into the test-bed,whether the wire was correctly connected by the students could be automatically detected.And the position of incorrectly connected wire could be showed on the digital display,based on which,the system could give scores accordingly.The system,which is simple and low cost,substitutes the instructor to check the wire connection so the previous problems can be solved.It can be widely applied to students＇ experimental equipment as it can edit different program according to different test-bed.
