应用Verilog HDL设计等占空比奇数分频器

Design of Equal Duty Ratio Odd Frequency Divider by Using Verilog HDL

在分析了与逻辑关系法、或逻辑关系法原理的基础上,以等占空比七分频器的设计为例,在Quartus II 9.0环境下进行了功能仿真,仿真结果验证了两种设计方法都能实现等占空比七分频器,并进一步说明利用这两种方法可以实现任意等占空比的奇数分频器设计。

Taking the design of equal duty ratio seven frequency divider as an example,using AND logical relation method and OR logical relation method to design seven frequency divider respectively.The function simulation is carried out in the Quartus II9.0environment.The simulation result shows that the methods of AND logical relation and OR logical relation are all right.It also shows that the two methods can realize any equal duty ratio odd frequency divider.
