数控分频器的设计数控分频器的功能就是当在输入端给定不同输入数据时，将对输入的时钟信号有不同的分频比，数控分频器就是用计数值可并行预置的加法计数器设计完成的，方法是将计数溢出位与预置数加载输入信号相接即可。-NC NC divider divider design of its function is when the input given different input data, input the clock signal will have different sub-frequency ratio, NC prescaler value can be used include parallel preset counter adder design is completed, the method is to count the number of overflow bit with preset load to the input signal phase.

通过FPGA驱动千兆以太网口，完成SPARTAN6上的UDP数据包闭环测试，即通过网口发送数据包到FPGA，FPGA内部将接收到的数据返回到PC机，建议测试之前添加ARP静态绑定，FGPA内部的IP以及MAC地址在ROM里的COE文档里可以看到，发送端添加了CRC以及整体CHECKSUM的计算(Driven by FPGA Gigabit Ethernet port, UDP SPARTAN6 data packet on the closed loop test, through the network to send data packets to FPGA, FPGA will receive the data back to the PC, the proposed test before adding ARP static binding, FGPA internal IP and MAC address in the COE document in the ROM where you can see, the sender adds CRC and CHECKSUM integral calculation)
