Document Table of Contents Step 5: Save Tile Plan Assignments

Once you have placed all IP components, and fixed any movable building blocks that you want to constrain, you save the constraints in Tile Interface Planner. Tile Interface Planner saves the fixed tile constraints to the project .qsf. The Compiler reads the .qsf assignments during the Logic Generation stage.
To save the tile plan assignments, follow these steps:
  1. Review and consider constraining any IP building blocks. To guarantee placement to exact locations, you must fix the IP building blocks connected to the IP pins to preserve those constraints in the .qsf, as Constraining IP Building Blocks describes.

  2. In Tile Interface Planner, click Save Assignments on the Flow control, and then click OK.
  3. Close Tile Interface Planner and return to the Quartus® Prime GUI. The tile IP assignments are visible in the Assignment Editor (Assignments > Assignment Editor) and in the .qsf file.
