1.6.3.5. Editing Pin Assignments for Presets

After you apply presets to IP, you can later view, edit, and remove those pin assignments for selected signals in the Exported Interfaces tab in Platform Designer. This action does not change the preset, but only changes the pin assignments of the exported system signals.

Note: Preset pin assignments are not yet integrated with other Quartus Prime software pin assignment tools, such as Pin Planner, Assignment Editor, Chip Planner, and Interface Planner. These other Quartus Prime pin planning tools do not currently show or allow you to modify any preset pin assignments that you make in Platform Designer. You can only view and edit preset pin assignments in Platform Designer.

To edit pin assignments for an existing IP preset, follow these steps:

Figure 52. Changing Preset Pin Location Assignments


  1. In Platform Designer, click View > Exported Interfaces. The Exported Interfaces tab displays the exported interfaces in the system.
  2. Under Exported Interfaces, select a specific exported signal. The Parameters field displays the signal and editable Pin assignment information. The interface Name and signal name match the exported_interface_name and exported_signal_name values in the preset .qprs file.
  3. To change the pin location or I/O standard for the signal, select a different Pin Location or IO Standard in the Pin field.
  4. To remove any pin constraint, right-click the signal interface name under Exported Interfaces, and then click Remove Current Pin Constraints.

    To change only the exported port name, you can do so in the System View tab. You must still make detail changes in the Exported Interfaces tab.

  5. After design compilation, review the exported preset pin assignments in the Quartus® Prime software Pin Planner.
