1.2.73. IGNORE_MAX_FANOUT_ASSIGNMENTS

Directs the Compiler to ignore the Maximum Fan-Out Assignments on a node, an entity, or the whole design. For HCII migration, the Maximum Fan-Out assignments can cause mismatches in Revision Compare. One can remove the Maximum Fan-Out assignments from the project but it is inconvenient/impossible as some assignments are embedded in the HDL sources. One should turn on this assignment to direct Quartus Prime to ignore the Maximum Fan-Out assignments.
