AFAIK sopc builder generates the sdc file by default, together with the .qip file which contains the hdl file references. At least this is true for the Quartus version 9.0sp2 I use.

Did you select TimeQuest as time analyzer?

I only see the SDC wich i made. I don't have one generated by SOPC builder. I use version 8.0.

I'll try shifting the SDRAM CLK but I probably need to reduce the speed of

the avalon bus with all those components on it. I was running it at 144MHz.
