详细介绍了VHDL的28个程序。从简单到复杂。介绍详细

数字钟，简单的数电应用，电子表源程序，常用也使用-watch

EDA技术及其应用《序列信号发生器的设计》，包括源文件。(EDA technology and its applications " sequence signal generator design, including source files.)

说明：  16级流水线型cordic旋转代码以及测试文件，亲测好用(16-stage pipelined cordic rotation code and test files, pro-testing)

数字信号处理的FPGA实现, 包括了FPGA基础知识，浮点运算，信号处理的FIR FFT等，附录包含源代码(Digital signal processing FPGA implementation, including the basic knowledge of FPGA, floating point operations, signal processing FIR, FFT, etc., the appendix contains the source code)

Ship navigation project

通信系统中的基带信号处理中的成型滤波器代码，已经通过编译。(Communication system baseband signal processing shaping filter code, has passed the compilation.)

软件开发环境：ISE 7.1i 仿真环境：ISE Simulator 1. 这个实例实现通过ISE Simulator工具实现一个具有两个方向共八个灯的交通灯控制器； 2. 工程在project文件夹中，双击traffic.ise文件打开工程； 3. 源文件在rtl文件夹中，traffic.v为设计文件，traffic_tb.tbw是仿真波形文件； 4. 打开工程后，在工程浏览器中选择traffic_tb.tbw，在Process View中双击“Simulation Behavioral Model”选项，进行行为仿真，即可得到仿真结果。-Software development environment: ISE 7.1i simulation environment: ISE Simulator1. Realize this instance through the ISE Simulator tool to achieve a total of eight lights in both directions of traffic lights controller 2. Works project folder, double-click traffic.ise Open the project document 3. rtl source file in the folder, traffic.v for design documents, traffic_tb.tbw is the simulation waveform files 4. to open a project, the project browser, select traffic_tb.tbw, in the Process View in the double hit

说明：  实现主干道交通灯显示，以状态机程序实现，并用数码管进行红绿灯倒计时的显示，内置计数模块，交通灯控制模块，数码管显示模块，并对各模块用电路图的方式进行连接。对于学习VHDL语言有所帮助。(The main road traffic light display is realized by the state machine program, and the digital tube is used to display the traffic light countdown. The counting module, the traffic light control module and the digital tube display module are built in, and each module is connected by the circuit diagram. It is helpful for learning VHDL.)

说明：  how to come ture a costas loop in FPGA with verilog,it is very useful on project

一个可以把信号拉长任意个CLk的VHDL源码例子。详见说明文档-A signal can be stretched any one CLk the VHDL source code examples. See documentation
