ID:18855 Atom location conflict. Nodes "<atom_name_1>" and "<atom_name_2>" from partitions "<partition_name_1>" and "<partition_name_2>" are placed in the same location, <location>

CAUSE: You attempted to compile a design with multiple nodes constrained to the same location. This is most likely to be the result of importing two or more preserved partitions that place/placed logic at the same physical location on the FPGA.

ACTION: Ensure your design does not import and preserve IPs/partitions with conflicting floorplanning constraints.
