各种常用模块的VHDL描叙实例，PDF格式

用VIVADO软件编写的，实现以太网芯片88E1510中的mdio控制模块代码，并且含有VIO仿真文件(Written in VIVADO software, the realization of the Ethernet chip 88 e1510 mdio control module of code, and contains the VIO simulation file)

SPI的Verilog实现(非常的全面和详细，还带有SPI算法的注解)(SPI in Verilog implementation (a very comprehensive and detailed, but also with the SPI algorithm annotation))

说明：  Verilog 入门,如果你要很了解Verilog你不用先谖完一本厚厚的书还弄不清楚Verilog到底在干啥事,这份资料有助於快速了斛Verilog(Verilog Basic, If you try very hard to understand verilog by read a thick book, try read this first you will get a quick understanding of verlog.)

系数为4的扰码生成器，并每四位扰码产生一个触发串并转换的触发信号，可用于4b/5b编码的触发信号。verilog程序，带test程序-coefficient of the four scrambler generator, and every four scrambler have triggered a string conversion and the trigger signal can be used to trigger 4b/5b coding signal. Verilog procedures, with test procedures
