I have tried to implement SGMII on DE4, and Arria 5 starter board, by using LVDS。 No successful record yet. So frustrated! The IP, altlvds_rx_top, generated by the IP catalog, has no output in parallel, even I can get a lock. And, for sure, the serial data was sent up to the input of LVDS. Why? Are there any one can give me a real example? I've tried to study all possible document on the web site Peter .
