but, how about the error:

Error: Node instance "ddr_control" instantiates undefined entity "auk_ddr_controller"[/b]

Because as far as I know, the 2C35 Nios II development board doesn't used DDR.

Thanks,

The CycloneII Developement Board does use DDR sdram. See the manual http://www.altera.com/literature/manual/mn...loneii_2c35.pdf (http://www.altera.com/literature/manual/mnl_nios2_board_cycloneii_2c35.pdf)

I found out that you have to inclued some vhdl files of the ddr sdram megacore component.

You can find them under <Your megacore directory>/ddr_ddr2_sdram-v3.3.0/lib.

Just add the .vhdl files to your QuartusII project.
