I am a new guy for VHDL programming. I want to use Virtext-5(XUPV5-LX110T) board to implement high data transmission to PC. I downloaded an open UDP_IP_Core from
opencore.org. I built a project and wrote a simble top level file for the UDP_IP_core. After I downloaded the bit file to Virtex-5 board, the transmission led always lights. However I can not receive any data from my PC. I have open the UDP port on my computer. But the Virtex-5 board still does not work. I have worked on this problem for nearly one week. But I can't solve this problem. The attached file my top file. Could someone help me solve this problem or give me some suggestion? Thanks so much.
