可编程逻辑器件实验报告

可编程逻辑器件实验报告.实验目的掌握数字时钟的设计方法掌握CPLD设计流程，设计60进制计数器，进行仿真同时观察控制效果方案设计与工作原理方案设计共用时钟和复位脉冲，DIVDER进行分频（此处仿真采用2分频，实际实验采用7分频），o_comm进行数码管显示控制，counter控制进制数（本实验采用60进制，各位十进制，十位6进制），encoder进行代码转换，将十进制数转换成相应控制数码管的16进制数，scaner控制4为数码管的输出顺序。如图所示：部分代码调试Counter：beginbegino_dataO 〈二o_data1 <=o_data2 仁o_data3,夺process(i_clkjbeginifi_rst=
