The Resource Assigner provides a tabular view of all GPIO resources in your chosen FPGA and information about them, such as whether they are used, the I/O bank, pad, and package pin, and the instance assigned to the resource.
  • The GPIO: Instance View shows all GPIO instances in your project.
  • The GPIO: Resource View shows all GPIO, LVDS, and MIPI RX or TX lane resources and the resources to which you assigned them.
Note: In the Efinity® software v2021.1, you can only view the resources used for LVDS and MIPI lanes in the Resource Assigner. You cannot change or assign resources in this view.

To assign a resource:

  1. Open the Resource Assigner by clicking the Show/Hide Resource Assigner button. The software opens to the Instance View, which lists all instances in the design.
    Note: Click Switch View to toggle between instance view and resource view.
  2. In instance view, you can assign pins or resources to the instance. Double-click in the table cell for the item you want to assign. The software displays a drop-down list of available selections.
  3. Select an unused resource, instance, or pin.
    Note: If you select a used resource, instance, or pin, the software makes the new assignment, which replaces the previous assignment.
  4. Press Enter.
