Sopc builder should have generated automatically a .sdc file for your system.

You must include it in your Quartus project.

You have to enable the settings for that? Cauze i can't find it in the main

directory.

Also make sure your checked the "Timing driven synthesis" in Analysis&Synthesis settings and follow the other guidelines reported by timing optimization advisor.

Final note: probably this is not your current problem, but usually you must drive the sdram clock pin with a phase lead relative to clock used by sopc system.

Probably you need to apply that in the sdc aswell. How?
