When targeting the Arria® 10 DDR4 IP and running the EMIF Toolkit in the Quartus® Prime Pro Software versions 19.2 or earlier, you may see the errors below.
Internal Error: Sub-system: EMITT, File: /quartus/sld/emitt/emitt_hardware_reader_nf_emif_131_impl.cpp, Line: 1905

To work around this problem, set the Interface ID parameter (in the Calibration Debug Options under the Diagnostics tab of the DDR4 IP) to a value equal to 10 or less.
This problem is scheduled to be fixed in a future release of the Quartus® Prime Pro Software.
