FSK调制通信系统的程序，比较实用，包括有限..

fpga配置锁相环完整程序，使用quartus IP核，Verilog语言。(FPGA configuration PLL complete program, Verilog language.)

通过一个计数器来实现输出信号的占空比要求，可以将duty_cycle分配到拨码开关上,LED分配到发光二极管上,然后调节拨码开关,即可看到LED的亮度发生变化.(The duty cycle of the output signal can be assigned to the dial switch by a counter, and the LED can be assigned to the light emitting diode. Then the brightness of the LED can be seen by adjusting the dial switch.)

OFDM中的IFFF模块实现，基于verilog实现，通过验证(OFDM module in IFFF)

xilinx spartan 6 pcie 仿真教程，v2.4版本，主要是讲解如何使用pcie core和自己的用户逻辑级联仿真。(xilinx spartan 6 pcie sim tutorial ，tell readers how to sim using pcie core and user app logic,tool:questasim)

从MIC输入一段音频然后，再从AOUT的接口播放出来的verilog 的代码-Input from the MIC for some audio and then AOUT interface from broadcast in the Verilog code

in this code very useful for designing real number concept

在ise开发环境下，建立顶层模块和子模块的层次结构，其实现的功能是一个可复位课暂停开始继续的建议秒表(In ise development environment, establish a hierarchy of top-level modules and sub-modules, and its function is to achieve a resettable class resumes proposal to suspend the stopwatch)

基于DVI协议动态全彩LED大屏幕发送卡设计与实现,成本比较低,效果很好,可以实现高清视频(Dynamic full-color LED large screen based on the DVI protocol send a card design and relatively low cost, good effect, and can achieve high-definition video)

说明：  此代码是由FPGA产生SPWM波的代码，简单易懂(use FPGA to generate SPWM)
