2.2.1. About Safety Logic Partitions and Logic Lock Regions

Altera recommends that you do not overlap any reserved Logic Lock regions. The Quartus® Prime Fitter does not use overlapping areas. The chip planner checks for overlapping regions.

A design may contain many safety partitions. However, do not create a safety partition within another safety partition. The Quartus® Prime Pro Edition software does not allow hierarchical safety partitions. The design creation flow detects this failure.

If you select an unsupported device for a design containing safety logic partitions, Quartus Prime gives an error during compilation. The error informs you that Safety IP is unsupported for devices other than Agilex 5.
