说明：  在Xilinx环境下编写的vhdl程序，实现推箱子的游戏任务，界面很漂亮。(Xilinx environment in the preparation of the VHDL program, realized the game viewing tasks, the interface is very beautiful.)

VHDL的源码100例，包括加法、减法、存储、触发等，是初学者、开发人员的必备手册-VHDL source code of the 100 cases, including the addition, subtraction, storage, trigger and so on, is for beginners, developers must Manual

quartus II 13.0 DDS工程文件，采用VHDL编写，可输出正交两路正弦信号。可以直接用modelsim-alter 仿真(quartus II 13.0 DDS project file, using VHDL written two orthogonal sinusoidal output signals. Can be simulated directly modelsim-alter)

verilog描述的基于LMS的自适应噪声消除器ANC算法。用于数字音频处理。(The verilog Description LMS-based adaptive noise canceller ANC algorithm. For digital audio processing.)

9对于输入密码锁的键，假设复位后七个灯显示" 0"，使用sw1、sw2、sw3、sw4 4，只需按下并松开任意sw1、sw2键，使七个灯显示值加" 1"，只要按下并松开任意sw3、sw4，将使七个灯显示值加" 2"

一个采用IIC协议，从ROM里面读数据的接口程序，采用verilog语言，状态机实现。(One with IIC protocol, which read data from ROM interface program, using verilog language, the state machine implementation.)

贪吃蛇程序，用verilog实现，可以运行只要修改一下相应的FPGA芯片类型和VGA接口相应的引脚(Snake program, using Verilog to achieve, you can run as long as the appropriate to modify the corresponding FPGA chip type and VGA interface to the corresponding pin)

此为EDA设计的分频器模块。可以实现三种不同的频率信号，可以通过使用者自由设置频率大小-This is the design of the divider module EDA. Can achieve three different frequency signals, users can freely set the frequency of the size of

PLL是数字锁相环设计源程序, 其中, Fi是输入频率(接收数据), 数字锁相技术在通信领域应用非常广泛，本例用VHDL描述了一个锁相环作为参考，源码已经调试过。编译器synplicty.Fo(Q5)是本地输出频率. 目的是从输入数据中提取时钟信号(Q5), 其频率与数据速率一致, 时钟上升沿锁定在数据的上升和下降沿上；顶层文件是PLL.GDF-digital phase-locked loop PLL design source, in which Fi is the input frequency (receive data), the digital technology in the field of communications is widely used, the cases described in VHDL as a PLL reference source has been tuned. Compiler synplicty.Fo (Q5) is the local output frequency. Objective is to extract data input clock signal (Q5), its frequency and data rate line, the clock rising edge of the data locked up and the descending; Top-level document is PLL.GDF
