Import options

Allows you to specify assignment import options.

• Imported assignments do not exist in current project— If the assignment file you are importing contains assignments not in the current project, this option allows those assignments to be created in the project. Assignments are imported from the Quartus Prime Settings File (.qsf) Definition or files that you specified in the Assignment source box in the Import Assignments dialog box. If the current compilation hierarchy contains multiple instances of an entity, the Quartus^® Prime software instantiates one set of assignments for each instance.
  Note:

  There are certain situations in which you may want to turn off the Imported assignments do not exist in current project option. For example, when you import Logic Lock assignments which create new regions in the target project. Thereafter, in the course of developing your project, you remove some of the imported Logic Lock regions, but eventually need to reimport the others. You would turn off this option, to ensure that the deleted regions are not recreated during the reimportation.

• Importe dassignments overwrite any conflicting assignments— Existing assignment values in the target project are replaced with the values in the assignment file you are importing.The Quartus^® Prime software reimports all non-Logic Lock assignments, and all assignments for the region(s) currently selected in the Logic Lock Regions window, into the current project. This option can be used to update Logic Lock regions that were previously imported and have not been renamed since they were imported. When you choose this option, the Quartus^® Prime software does not update the region's child Logic Lock regions unless those regions are also selected in the hierarchy.
• Imported entity assignments replace current entity assignments— Deletes matching entity assignments in the target project before importing new assignments. When this option is turned on, assignments in the assignment categories turned on in the Available assignment categories list that have matching assignments in the imported assignments file, are replaced with the assignments in the imported file. However, assignment categories turned off in the Available assignment categories list that do not have matching assignments in the imported assignments file are deleted without new assignments being imported.
