11.2 EDK XPS_LL_TEMAC_v2_02_a - The constraints are not backward compatible with v2.00.a of the core
Description
Keywords: soft, revup, failed, constraints
I receive the following errors upon revup of the core from EDK 11.1 to EDK 11.2:

Solution
The xps_ll_temac Core incorporates the design of the CORE Generator Tri-mode Ethernet MAC (soft TEMAC) Core. xps_ll_temac_v2_00_a uses CORE Generator core version 3.4, while xps_ll_temac_v2_02_a uses CORE Generator core version 4.1.The CORE Generator core clocking design was simplified in the newer core, reducing the number of files and some levels of hierarchy in the design. These changes in hierarchy caused the path names in the constraints to change, resulting in the new recommended constraints.
Please use (Xilinx Answer 32713) to update the TEMAC constraints with the current recommendation.
