I have a project which was successfully synthesized then archived.
After unpacking the archive and opening the project, the Synthesis run status is shown as "out of date".
In Vivado Design Suite 2013.2, the status is correctly handling the source file order changes in a live project session. However, while opening an existing project with sources that have changed location, the file order change is incorrectly calculated and causes the project to be falsely shown as out of date.
In Vivado 2013.2 tool and earlier, the "Force up to date" option can be used to correct the status.
This issue has been fixed in Vivado Design Suite 2013.3.
