可直接用于zedboard上的串口通信，利用zynq7000的pl部分实现一个简单的UART串口通信(Can be used directly on the zedboard serial communication, the use of zynq7000 PL part of the realization of a simple UART serial communication)

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 )

数字时钟6位数码管显示。主要器件为74ls48和74ls160 /74ls161。功能：1.显示时、分、秒。2. 可以24小时制或12小时制。3. 具有校时功能(Digital clock six digital tube display. Main components of 74ls48 and 74ls160/74ls161. Features: 1. Shows hours, minutes, seconds. (2) a 24-hour or 12-hour clock. 3 a school function)

采用xilinx的ROMIP核产生类似正弦信号，经过FFt后可以观察结果(Using the xilinx ROMIP nuclear generating similar sinusoidal signal can be observed through the results after FFt)

基于verilog-a的自建模型，可以作为任何代建模型的参考，理解hspice模型的构成，内在根本机理。
