NIOS 2 and DE@ board examples

Hello to all,

I'm looking for a good example file(s) with NIOS 2 and the DE2 board. The example files on the cd are all VHDL files, but what I'm looking for is an example file(s) as a block diagram. I'm a starter in all of this and with de UP3 board there where some example files with nios 2 and the UP3 board as a block diagram.

I hope that some of you can help my with a good example file(s) for the DE2 board.
