Internal Error: Sub-system: LCHIP, File: /quartus/legality/lchip/lchip_clock_region_placement_counter.cpp, Line: 2060


Due to a problem in the Intel® Quartus® Prime Pro Edition software version 19.1 and later, you may see this internal error when compiling designs targeting Intel Stratix® 10 devices.


To work around this problem, add the following assignments to your .QSF (Quartus Settings File)

  • set_global_assignment -name PHYSICAL_SYNTHESIS OFF
  • set_global_assignment -name ADVANCED_PHYSICAL_RETIMING PRE_PCA

This problem is scheduled to be fixed in a future release of the Intel Quartus Prime Pro Edition software.
