So it seems that you do NOT have a custom IP core, but want to use Altera IP cores and then just write software.

You do not have to bother in realizing a SDRAM controller, it is already provided by Altera.

You just need to istantiate it in the SoPC builder and then connect it to i/o pins.

My best advice is to take a look to the NIOS examples on the altera website or on the developement board cd, and get started with a simple SoPC system which has a NIOS core, a sdram controller and some PIO.

After you succesfully build a NIOS SoPC, you can write your C software using the Eclipse software build tools for NIOS (which is distributed for free by Altera, https://www.altera.com/download/software/nios-ii/11.0)
