verilog语言,quartus下实现频率计,内附原理图以及详细说明。

一共6个.v模块,其中一个是top,其余都是子模块。

测量频率的原理很简单,对一定时间内待测信号的上升沿的个数进行记录即可。

单位khz,四位数码管,小数点可以处于其中任何一位,假设数码管由高到低定义成HEX3,HEX2,HEX1,HEX0,那么当hex0的小数点点亮时,表示xxxx khz,hex1的点亮时,xxx.x khz,依次类推。

为保证精度,当时xxxx khz时,最小分辨率应该是1khz,所以此时基频信号应该是1khz。

上升沿计数时间应该是1ms。

X.xxx khz时,最小分辨率是0.001khz,也就是1hz,基频应该是1hz,上升沿计数时间应该是1s。-use verilog language,a frequency detector.
