Hi every body 

 i am performing my graduate project for my computer engineering certification .  I am making router by using de2 board  but as we know router has multiply port and I will make two ethernet port by using triple speed ethernet 9.1  but if I select more than one port in triple speed ethernet configuration .  that will cause no fifo memory in this controller and i must use independent memory connected to triple speed ethernet called multi channel shared memory fifo   but i don't have any idea how i can connect this memory with triple speed ehternet  please if any one have any idea help me and i prefer to give me example contain multiply ethernet port by using triple speed ethernet  thank you for your reading

I have the same question,and I also don't konw how to solve the follow problem:"error:triple_speed_ethernet_0.receive_0 and multiplexer_0.in0 must be on the same clock domain,since they're connected.

You must give the same clock to the triple speed ethernet mac and the multiplexer. If you want to use two different clocks, then put a dual clock FIFO between them.
