software exports the LogicLock region assignments for the entire design.
You can specify subdesign entities to export in the Export assignments
hierarchy path box. See Figure 4.
Figure 4. Export Assignments Dialog Box
When you import LogicLock region assignments, the Quartus II software
traverses the compilation hierarchy, starting at the current compilation
focus. If the current project contains multiple instances of a lower-level
entity, the Quartus II software instantiates the assignments imported for that
lower-level entity once for each instance.
To prevent placement conflicts, the Quartus II software assigns imported
top-level LogicLock regions to floating locations. However, it preserves the
location of imported child regions relative to their parents. Figure 5 shows
the Import Assignments dialog box.
