In addtion to the suggestions made in your previous thread https://www.edaboard.com/threads/280127/#post1199849

There's a certain risk that the error is brought up by an invalid design that isn't expected by Quartus. In this case removing design parts incrementally can usually help to identify the problematical design construct.
