1.10.12. Register Packing and Partition Boundaries

The Intel® Quartus® Prime software performs register packing during compilation automatically. However, when incremental compilation is enabled, logic in different partitions cannot be packed together because partition boundaries might prevent cross-boundary optimization. This restriction applies to all types of register packing, including I/O cells, DSP blocks, sequential logic, and unrelated logic. Similarly, logic from two partitions cannot be packed into the same ALM.
