verilog HDL程序设计开发实验

实现数字变下频的matlab程序，CIC,HB,FIR滤波器代码都在其中(Realize digital variable frequency under matlab, CIC, HB, FIR filter code in it )

Disparity mapp code in VHDL

滤波器 Generaic FIR Filter(Generaic FIR Filter)

关于FFT实现的Verilog代码，(FFT realize on the Verilog code,)

说明：  使用DE2实现DDS，步骤简单，配置管脚可自查看(Using DE2 to realize DDS, the steps are simple and the pins can be self-checked.)

xilinx的时序约束实验，通过阅读本文档，你可以用全局时序约束来轻松提高已有的项目的系统时钟频率，同时你还可以用映射后静态时序报告以及布局布线后静态时序报告来分析你的设计性能(Xilinx timing constraints of the experiment, by reading this document, you can use the overall timing constraints to easily enhance existing projects the system clock frequency, at the same time you can also use static timing report after mapping, as well as after placement and routing static timing analysis report to you design performance)

这是一个学习verilog HDL的好资料，适合于初学者，讲解详细，从浅入深，学好这个语言，是学习硬件描述语言的好东西，好资料！

DSP与FPGA时序接口模块，已经经过测试，保证读写稳定(The Interface of DSP to FPGA)

vhdl 实现fpga 闪灯控制 流水线闪灯 还用signalTAP进行检测，给初学者参考(vhdl fpga flash control lines to achieve flash is also used signalTAP testing, to advanced users)
