Qsys Nios project is ambiguous in Quartus???

The Qsys migration guide says I have to add the QIP file generated by Qsys to the Quartus project. When I do this, quartus errors saying the Nios system instance is ambiguous because there is nios_system.v file in both the db folder and the nois_system folder generated by Qsys. This is true but why is there any confusion??? Quartus copied the file to the db folder itself. I started from a completely clean project folder with no db folder nor nois_system folder. Qsys generated the nios_system folder and the associated QIP file and Quartus generated the db folder with the nios_system.v file in it. What is wrong with these tools???

Hi, 

 

Do you have the .qsys file included in your project files? If so, try removing it from the project files. I had the same problem and that sorted it.

Hi Mark, 

Thank you so much for the help. You were right. I had the qsys file included in the project files.

Hi Greg, 

 

Glad it worked and thanks for reporting back. It sure had me scratching my head for a long time and I found the solution accidentally.
