vhdl经典源代码――时钟设计，入门者必须掌握

一本很好的教程，适合初学者,里面有详细的教程，很值得一看！！(A good tutorial, suitable for beginners, there are detailed tutorials, it is worth a visit!!)

这是执行高速的代码通用异步收发器代码是用VHDL写的语言.UART是一种在传输端进行并行输入和串行输出，在接收端进行串行输入和并行输出的算法。

此文件给出了一个多功能交通灯的VHDL代码实现，可作为电赛的准备材料-This paper gives a multi-functional traffic lights to achieve the VHDL code can be used as electric materials Cup preparations

基于FPGA的SOPC嵌入式的流水灯的实现。-Embedded FPGA-based SOPC flow light implementation.

vhdl波形发生程序.实现4种常见波形正弦、三角、锯齿、方波（A、B）的频率、幅度可控输出（方波 A的占空比也是可控的），可以存储任意波形特征数据并能重现该波形，还可完成 各种波形的线形叠加输出。 -vhdl waveform occurred procedures. 4 achieve common sinusoidal waveform, 1.30, sawtooth, square-wave (A, B) the frequency and amplitude control output (square A duty cycle is also controllable), can store data of arbitrary waveform characteristics and able to reproduce the waveform, but also through a variety of linear superposition of the waveform output.
