add .qsys is good, add .qip of the Qsys is bad

Hi,

When I add the .qip generated by Qsys-edit in my Quartus project,

as said in PDF manuals,

and then develop software for that, I get mismatched timestamps 

Expected system timestamp: 1348579121
Connected system timestamp: 1348748439

Difference is near 3min 50s.

When I add the .qsys in my quartys project (previously removed .qip from project),

timestamps match.

But Quartus resynthesizes the Qsys component wich takes a few minutes.

Adding .qip save compilation time, it would be better if timestamps match. Just for you Altera developpers.

Kindest regards.

    i have never seen this error, and cant understand why you would either. I would suggest checking that the qsys file is removed entirely from the qsf to ensure the qsys system is not being regenerated during compilation.

    When I remove .qsys and add .qip in project settings, the .qsf file is properly regenerated : it contains no reference to .qsys.

    But I may find : my qsys system is not at the project root path, it is in a custom "src" subdirectory. Maybe the (minor) problem is this.

    OK, that was the problem.

    I saved my Qsys in my Quartus project root directory, deleted the old qsys, adapt project files settings, and everything is correct. :)

    quartus 12.0sp1 + nios ii web edition

    qsys from scratch (no sopc to qsys migration : that is to say tri-stated components are from qsys)
