随机数生成代码的Verilog，Xilinx FPGA

使用nios2点亮一个led灯，使用软件quartus13.0，开发板de2-115(nios2 led quartus13.0 de2-115)

利用最新的嵌入式开发工具EDK，在FPGA 中完成对PDIUSBD12 的硬件定制和固件编程，从而在FPGA 中实现U S B 控制器， 并最终完成U S B 的枚举过程、驱动程序的开发和简单的应用。(Using the latest embedded development tools, EDK, in the FPGA completes its PDIUSBD12 custom hardware and firmware programming, in order to realize USB controller in the FPGA, and ultimately complete the USB enumeration process of driver development and simple应用.)

说明：  串口通信通用模块，FPGA Verilog语言 ise，vivado环境(uart,FPGA Verilog, ise,vivado)

实现Verilog编程，实现超声波测距模块实现测距功能，并将测得的距离显示在数码管上(Verilog programming is realized, ultrasonic ranging module is realized, and the measured distance is displayed on the digital tube)

使用spi模式初始化w5100，实现了快速以太网的初步建立(Using the spi mode initialization w5100, to achieve the initial establishment of a Fast Ethernet)

verilog编写的基于CA算法的m序列发生器，其中验证了多种CA系数来实现m序列。(CA-based algorithm written in verilog m-sequence generator, which verify the CA factor to achieve a variety of m-sequence.)

 ；随着CMOS技术达到其物理极限，新技术

说明：  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.)
