mtn,
Just search for "Nios II Errata" on the main Altera page:
http://www.altera.com/support/ip/processor...osii-50-er.html (

Then, from the errata, you'll see:

Build errors after changing component names in SOPC Builder
If you rename components in the SOPC Builder system and then regenerate the SOPC Builder system, Nios II IDE system library projects based on that system will have build errors.
Workaround: After regenerating the SOPC Builder system, create a new system library project for the SOPC Builder system. Alternately, you can delete the system library project from the workspace without deleting the contents from the file system, and then re-import the project, selecting the appropriate SOPC Builder system.[/b]
