Need help : implement Gigabit Ethernet

hi all,

first thanks for your help, especially daixi

now the design for GbEth is working well, but I have now idea how i can continue

i try to send 8bit every 40 ns from a camera but i absolutly don't know how to do that, first i erased the component i don't need (as led, switch ...) but i always get an error about a multiple fan-out for ddr's data

now i'll try to add to the current design something for sending my byte (my pixels values) to the pc

any ideas will be welcome, thanks in advance
