10GbE PCS Implementation

Hello,

Is there anyone who have experience in implementing 10G Ethernet PCS?

Have anyone successfully implemented a working 10G Ethernet PCS in Virtex-II Pro devices using Xilinx XAPP775? If yes, were there any modifications in the PCS submodules?

Are there any other 10GbE PCS IPs that are available for Virtex-II/Virtex-II Pro devices?

Thanks,

-Markus
