Thank you, primiato and socrates.......i think i was success building my system with sopc buider and i allso use PLL to create dependen clock for sdram controler block....

i saw all examlple use verilog HDL to do that......anđ as primiato said to me that

"do you want to read/write it from a custom ip/design you are developing or do you want to access it from a nios softcore?"

so i think i want to access it from a custom IP.....because of your advice:-P

if you dont mind you can teach to me about "custom ip/design"...

i really need that because :cry:my project have to finish last month...
