Vivado 2013.3 set_max_delay constraint not being applied correctly when used in Out of Context (OOC) flow

Description

When creating an OOC workflow, the set_max_delay constraint set in the DCP is not being retained correctly in the Top module.

If the set_max_delay value is larger than the clock period, then the value is dropped and the clock period is used for the path instead.

Solution

The timing system should not change the value of a constraint when a conflict occurs.

The issue is fixed in the 2014.4 release.
