用数码管显示时间的数字电子钟verilog编写

USB设备接口的驱动程序，采用verilogHDL语言编写，并包含相关说明资料(USB device driver interface, using verilogHDL language, and contains descriptive information)

Avt_S6LX9_MicroBoard_UCF_110127，有关xilinx spartan6开发板的相关参考设计。(Adding Custom IP to an Embedded System, the relevant reference on xilinx design.)

电梯的vhdl设计，6层楼含开关门，警报，内部请求，外部请求-Vhdl elevator design, six floors with switch doors, alarm, internal requests and external requests

USB 1.1 PHY的代码，verilog语言 USB 1.1 PHY的代码，verilog语言-USB 1.1 PHY code, verilog language USB 1.1 PHY code, verilog language

FPGA UART transmit and so on

说明：  该资料是用vhdl编写的按键消抖程序，按键消抖在使用按键的数字电路中非常重要，如果不对按键信号进行处理，有可能会出现大量错误的按键信号。文件key_xd.vhd是按键消抖程序，文件key_xd.vwf是仿真波形文件。该程序已经通过仿真测试，并且在电路板上调试通过，效果理想。(The information is written in the key consumer vhdl shaking procedures, key consumer shaking in digital circuits using the buttons is very important, if not key signal processing, there may be a lot of the wrong button signal. File key_xd.vhd is key consumer shake procedure is the simulation waveform file key_xd.vwf file. The program has been tested by simulation and debugging in circuit board by, the results are satisfactory.)

FFT处理器的FPGA设计方法，适合做信号处理的技术人员参考，用FPGA实现-FFT processor, FPGA design, suitable for signal processing technology for reference, using FPGA to achieve

用verilog语言编译的pci协议实现，而且有具体的电路图(Compiled with the verilog language pci protocol implementation, but also the specific circuit)

四位密码锁，移位显示，可以设置和更改密码。-4 lock, shift, it can be set up and change your password.
