To determine whether the worst failing setup path is due to hold fixing, review the hold timing of that path. In the Vivado IDE, right click and report timing on source to destination. As opposed to doing the setup timing analysis, it is important to look at the hold timing. Once you have the hold report, verify the requirement and ensure that additional delay was not added on the path to be able to meet hold.
