该项目用来测量频率。它有三个范围，其中包括 0.01 赫兹 ~ 1 Hz，1 ~ 100 Hz 和 100 ～ 10000 Hz。这样的结果将是最好的程序能自动调节到最佳的范围内。这个项目是在 Altera 软件 8.1 上进行验证。

这是个关于verilog入门的文档，有同志对verilog感兴趣，可以下载此文档，以供参考。(This is a verilog entry on the document, there are comrades of the verilog interested, you can download this document for reference.)
