Hi - I dont see any QSys-eness about that download it cites SOPC builder in readme.txt (unless I am blind and cant see the QSys projects)
I have been trying for 2 days now to port it to QSys ... the SOPC import facility just plain old doesnt work straight up as is.
Has anyone got a 3C25 NEEK or starter board project running with the DDR??

Hi Steve,
I see what you mean about the readme file - it doesn't mention anything about Qsys. Must be an old design that they ported to Qsys from SOPC and didn't update the documentation. Might as well get used to it if you want to work with Altera, though. This forum is about the only way to get any answers and solutions to the multitude of "issues" that lurk around every corner.
However, this particular example that I referenced really is designed around Qsys rather than SOPC Builder and it actually does work on the Cyclone III NEEK dev kit. I presume you downloaded the niosii-ethernet-standard-3c25.zip file and extracted the files. Look carefully and you will see three Qsys files:
eth_std_main_system.qsys
ethernet_system.qsys
peripheral_system.qsys
To view the Qsys desgin, launch the niosii_ethernet_standard_3c25.qpf file in Quartus II, then click on the Qsys icon in the toolbar, or select Qsys from the Tools menu. This will call up a dialog box to select which Qsys file you want to load into Qsys. Select eth_std_main_system.qsys to view the main design. This is a hierarchical design which has two submodules. To view those you have to open their respective .qsys file in Qsys.
Please let me know if this doesn't work or have further questions about the example.
