I have a design I plan to use Altera Triple Speed Ethernet MAC IP. In the PCB, the FPGA is connected with medium dependent interface (MDI), there is no physical connection between RGMII interface with FPGA. So MDI is my only choice, in here:
http://www.altera.com/products/ip/iup/ethernet/m-mtip-1000mbps_fulldup_ethermac.html Altera mentioned it seems they support MDI since: Serial 1.25-Gbps medium dependent interface (MDI) (optional) implemented with Altera Stratix GX-embedded serializer/deserializer (SERDES) But in their IP configuration, there is no option to make it work with MDI. I wonder have anyone has experience using this IP work MDI? Thanks a lot.Link Copied

The link you posted is for an IP core from a 3rd party. It is unrelated to Altera Triple Speed Ethernet IP core.

Which part are you having trouble with? There is no "MDI" checkbox in the GUI, you just need to select the correct variant per the manual.

--- Quote Start --- Did I miss something? --- Quote End --- Sorry, I can't help with that - it sounds like you're getting a different copy of the file than I am when I click the link you gave. The one I'm getting is labelled 2014.06.30, and on page 7-23 there is not any MII mentioned at all. Good luck. Edit: in case there is a terminology problem, page 7-23 (Chapter 7 Page 23) is the 138th page within the PDF. "page 7-23" does not mean pages 7 through 23 (which would consist of the end of the table of contents through page 2-5).

I think you mentioned is page 7 to page 23. I will check it and post here if I have more questions. Thanks.
