本程序为七分频数字电路的实现，采用VHDL语言编程，采用常见的奇数次分频方法实现，进仿真证实可用。其他奇数次可以直接修改程序中相关参数值即可直接移植引用-This procedure is the seventh-frequency digital circuits implemented using VHDL language programming, using a common method to achieve the odd division into simulation confirmed available. Other odd number can directly modify the program parameter values can be directly transplanted references
