verilog写的程序，是带按键消抖程序。。对于新手具有参考-verilog write the program, with key debounce program. . A reference for the novice

按键消抖程序，用Verilog硬件描述语言编写，实现了按键消抖动作-Buffeting eliminate key procedures, using Verilog hardware descr iption language, the realization of the keys for jitter elimination

实现简单的滤波，一般用于按键的消抖，简单实用，直接调用就可以实现轻松地滤波。-Simple filtering, generally used debounced keys, simple and practical, direct calls can be achieved easily filtered.
