verilog实现的“状态机实现AD574数模转换”-verilog to achieve a " state machine to achieve AD574 digital-analog conversion"

Xilinx开发板ML505的DDRII示例程序，使用Verilog，调用MIG，编译环境ISE11.1(Xilinx ML505 development board of DDRII sample program, using Verilog, called MIG, build environment ISE11.1)

说明：  VHDL语言100例详解。详细讲解了用VHDL语言进行数字电路和数字系统设计的知识。用100个实例，不仅进行基础的门电路设计，而且还有较为复杂的数字系统设计。这些实例可以直接被调用。(VHDL Elaborates on 100 cases. Detailed account of VHDL for digital circuits and digital systems design knowledge. With 100 examples, not only for infrastructure gate design, but also more complex digital system design. These examples can be called.)

TCM解码，VHDL代码，是我在工作中做的工程代码，时序稳定，里面有syn以及软判决的算法，经典-TCM decoder, VHDL code, yes, I do work in the project code, timing stability, There are syn and soft-decision algorithm, classic!

原创。掷骰子游戏，VHDL，quartus，北京邮电大学数电实验，实现随机掷骰子游戏，在数码管显示点数，点阵显示输赢，有开机动画以及开机音乐，可实现多人游戏等(games, VHDL, quartus,experiments of BUPT, pure originality,random game, in the digital display dots, dot matrix display winning or losing, there are boot animation and boot music, multiplayer gaming can be achieved)

说明：  2018全国大学生FPGA创新设计大赛南京总决赛封闭测试题目，以及自己编写的verilog和testbench，欢迎学习借鉴(The closed test topic of the 2018 National Undergraduate FPGA innovation design competition Nanjing finals, as well as Verilog and testbench compiled by ourselves, are welcome to learn)

典型事例，从网上down的，希望对大家有用，-Typical examples, from the Internet down, and I hope useful for everyone,

在实现 OFDM 中，必须有筛选器，以提高无线电信号的质量。一般情况下，筛选器应用于 OFDM 的类型是 FIR 滤波器。FIR 滤波器是方便使用，因为线性相位的未来。所以，我研究它与实现 FIR 滤波器 VHDL 语言一轮。这段代码是完全测试。但我是节约资源的 FPGA 改进范围。

I2C的VHDL源码，从机模式，编译通过。-I2C the VHDL source code, from the mode, the compiler through.
