Assignments to export

File name—Specifies the name and path of the Quartus Prime Settings File (.qsf) Definition to which the Quartus^® Prime software should write the assignments. By default, the file name matches the entity name of the entity instance in the Export assignments hierarchy path box, and the file path is <project directory>/atom_netlists/. To prevent current project files from being overwritten, the Quartus^® Prime software does not allow you to specify the current project directory as the export file path.
Export assignments hierarchy path— Specifies the full hierarchical path name of the entity instance whose assignments you want to export. When you specify an entity instance, you direct the Quartus^® Prime software to export only assignments belonging to that entity instance and its sub-entities. By default, the export assignments hierarchy path is the project's top-level design entity. However, you can set it to a lower-level entity by dragging and dropping the lower-level entity's name from the Hierarchy tab of the Project Navigator, or by typing the lower-level entity's full hierarchical path name in the Export assignments hierarchy path box.
