When a design has multiple MIG instances included in the same design AND they have Out-of-Context (OOC) disabled for each instance the below critical warnings are seen due to same file name being used in both of the MIG cores:
CRITICAL WARNING: [filemgmt 20-1741] File "riuMap.vh" is used by both "mig_0" and "mig_1", but with different contents. This may lead to unpredictable results.
Please use the report_ip_status command to resolve the differences or synthesize the modules independently. (Files are: "/proj/dsv_xhd/pparata/work/temp/run/multi_mig/example_top/mig_0_example/mig_0_example.srcs/sources_1/ip/mig_0/rtl/map/riuMap.vh" and "/proj/dsv_xhd/pparata/work/temp/run/multi_mig/example_top/mig_0_example/mig_0_example.srcs/sources_1/ip/mig_1/rtl/map/riuMap.vh")

This issue only occurs when OOC is disabled.
To work around the issue enable OOC for each MIG instance or use the following manual work-around:
