When upgrading a locked IP to a new version of Vivado, the following error message might be seen:

ERROR: [Mig 66-119] Phy core regeneration & stitching failed. Please check vivado.log and debug_core_synth.log files in the directory: /proj/ipmig2/rakeshb/Upgrade_Flow_testing_2016.1_to_2016.4/ddr4_cmc_50tests_upgrade/ddr4_cmc_50tests_upgrade/SN6_virtexuDDR4_926MHz_72bit_ecc_ssit_BFM_XSDB_EN/vivado/impl/SN6_virtexuDDR4_ooc_en_example/SN6_virtexuDDR4_example/SN6_virtexuDDR4_ooc_en_ex/SN6_virtexuDDR4_ex/SN6_virtexuDDR4_ex.runs/impl_1/.Xil/Vivado-29140-xhd-lin64re91/29140 to debug the problem.

This error can occur as a result of the address width for the targeted DDR4 part changing between releases. Only the following DDR4 RDIMM parts are impacted:

  • MTA18ASF1G72PZ-2G1
  • MTA36ASF2G72PZ-2G1
  • MTA18ADF1G72PZ-2G1


If this error message is seen and you are targeting one of the impacted DDR4 RDIMM parts, then please regenerate the DDR4 IP from scratch in the new version of Vivado to resolve the issue.
