AR# 52213 MIG 7 Series - Critical warnings are seen in Vivado regarding XDC constraints

Description

Version Found:MIG 7 Series v1.7.a
Version Resolved:See(Xilinx Answer 45195)

Criticalwarnings are generated as a result of Vivado pulling in overlapping constraints from example_top.xdc and <user_design>.xdc. The example_top.xdc constraints should only be used with the MIG generated example design and the <user_design>.xdc should only be used without it. This also occurs when using the "Open IP Example Design" option in the Vivado GUI.

Solution

To work around the critical warnings, you can run the vivado.tcl script provided in the /example_top/par/ or /user_design/par/ directories. The overlapping constraints can also be removed from the XDC file to bypass the critical warning messages or ignored.
