SDRAM controller in Nios Design

Hi, I have a basic doubt. In the Nios design, what SDRAM controller do we use? Do we use the simple SDRAM controller or DDR3 SDRAM controller with UNIPHY? What is the difference between the two...

I see. So my board has a DDR3, so thats that.

Also, Where can I find how to make the pin-connections required for the sdram controller?

I wrote a couple of example designs; one for SDRAM on the DE0-nano board and one for DDR3 on the BeMicro-CV board. Synthesize the designs and read the scripts and notes. They have all the information you are looking for.

Look at de0_nano_sdram.zip:
