Can't compile tutorial: Introduction to the Altera Qsys System Integration Tool?

Hello Rodo

I've got a similar error on the same tutorial but using Quartus 13.1. Its is seems that compilation fails due to Error (12006).

I've followed this https://www.altera.com/support/support-resources/knowledge-base/solutions/rd03142013_949.html

That solved my problem. You just need to add all files from the assignments --> settings --> files menu after putting the nios_system.qip in you project folder.

Then compile the project.
