Description
Due to a problem in the Quartus® II software version 13.1, you may see this error message when you compile a revision whose name is different than the project name.
Resolution
To work around this problem, perform the following actions:
- Switch to the revision with the same name as the project (creating that revision if it doesn\'t exist)
- Switch back to the other revision before compiling
Alternatively you can delete the db and incremental_db directories.
This problem is scheduled to be fixed in a future release of the Quartus II software.
