I want to Test Designs Using Stratix IV GX FPGA Development + Dual xaui SFP HSMC
this required (hsmc_loopback.sof)
How can i find this file

From its name, hsmc_loopback, it implies loopback at the HSMC. This is not what you want for testing a XAUI/SFP+ HSMC board. Terasic likely have an example for that.
I am sure there are several layers of loopback;
1) A simple loopback where data from SFP+ is received over XAUI and then sent back over the link.
2) A more complex loopback where data is received as 10GbE packets and the contents checked.
You'll want to perform both sorts of checks.
Cheers,
