Informations about DUAL XAUI TO SFP+ HSMC BOARD/BCM8727

Hello,

Are you using multiple SFP+ interfaces?

I have a Stratix V GX Development Board and I've successfully used one SFP+ interface on channel 2. When I try to instantiate two 10 GbE Design Example modules on qsys and connect each of them to separate xaui channels, quartus give me this fitter error:

-Error (175001): Could not place auto-promoted clock driver

Does anyone have any clue of what may be this error?

Thanks!
