  • Create a copy of the existing MMCME2_ADV.v file (e.g., MMCME2_ADV.v.old)
  • Move the file to the directory: <vivado_install>/data/verilog/src/unisims/

Move the VHDL file into the source libraries:

  • The file is MMCME2_ADV.vhd
  • Create a copy of the existing MMCME2_ADV.vhd file (e.g., MMCME2_ADV.vhd.old)
  • Move the file to the directory: <vivado_install>/data/vhdl/src/unisims/primitive/

Re-run the library compilation process for all external simulation tools:
