内容有VHDL语法总结及相应的实例应用，每个程序我都亲自试过，特别适合初学VHDL的同学们。常用的程序有 设计一个M序列发生器，M序列为“11110101”、 设计一个彩灯控制器，彩灯共有16个，每次顺序点亮相邻的四个彩灯，如此循环执行，循环的方向可以控制。设计一个跑马灯控制器。一共有8个彩灯，编号为LED0~LED7，点亮方式为：先从左往右顺序点亮，然后从右往左，如此循环往复等等。这些都是我在考试前熬夜总结的，很有用。如果配合开发板用的话，那就更好了- VHDL syntax summary content and the appropriate application instance, every program I have personally tried, especially for students of beginner VHDL. Common program has designed a sequence generator M, the M series is　11110101 , a lantern controller design, a total of 16 lights, each sequence of four adjacent lights lit, so the cycle execution cycle direction can be controlled. Marquee design a controller. A total of eight lights, numbered LED0 ~ LED7, the lighting way: first　left to right order of light, and then　right to left, so the cycle and so on. These are all I stay up all night before the exam summary, very useful. When combined with the development board, then so much the better
