Hi all.I am using de-2 board. I am trying to access the SDR sdram on board without using a nios system(but still using a SOPC builder). Tutorial(s) provided by altera says to use a -3 ns delay in order to have a correct timing with the controller; but even if I drive the sdram controller with a -3ns @50MHz clock, ito doesn't work. ow, the question is.. How can I find the right delays by own? I've tryied to run timing analysis but I wasn't still able to find the right timing. It'so frustrating.
