说明：  高速宽带数字调制技术的研究，该论文也是非常经典的，希望对大家有帮助(High-speed broadband digital modulation technology, the paper is also very classic, I hope all of you help)

基于FPGA的正弦脉宽调制波vhdl代码，同时输出正弦波与SPWM(Sine pulse width modulation wave VHDL code based on FPGA, at the same time with SPWM output sine wave)

verilog实现的数字跑表 精确到10ms-verilog digital stopwatch to achieve accurate to 10ms

用verilog HDL语言，通过一个4位移位寄存器实现一个信号转化为HDB3码并进行测试 -Using verilog HDL language, through a 4-bit shift register realization of a signal into HDB3 code and test

一款非常实用的8051IPcore,本人现在做soc的控制部分就是它。(A very useful 8051IPcore, I now control part of the soc is doing it.)

zedboard的资料说明书，可以帮助你理解(zedboard data sheets, can help you understand)

基于FPGA的交通灯的设计 有Verilog HDL 源码、仿真图与引脚配置图，已下载实现 -FPGA-based design of traffic lights have Verilog HDL source code, simulation map with pin configuration map has been downloaded realize

SPI接口测试程序，Xilinx参考设计，ML507硬件测试通过.(SPI interface test code，Xilinx reference design，tested on ML507 platform.)

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
