Due to a problem in the Intel® Quartus® Prime Pro software version 18.0 or earlier, when a partition is placed in row clock region adjacent to EMIF/PHY Lite/LVDS interfaces in one project (or in developer project) and is reused using the QDB_FILE_PARTITION assignment into another project (or into consumer project) you will see the following Internal Error:
Internal Error: Sub-system: LAB, File: /quartus/legality/lab/lab_nd_config_creator_module.cpp, Line: 1006
- A clock sector defined by the green box in Figure. 1
- A row clock region is half-clock sector wide and one LAB row tall represented by the red dotted box in Figure. 1
- In the consumer project, if the reused partition has a placement in this region, you may see the above Internal Error.
