3.2.5. Updating Intel® Quartus® Prime with I/O Designer Pin Assignments

As you fine tune your board design in I/O Designer, changes to signal routing and layout are likely. You must import any routing and layout changes into the Intel® Quartus® Prime software for accurate place and route to match the new pin-out. The I/O Designer tool supports this flow.
Figure 32. Importing I/O Designer Pin Assignments

To import I/O Designer pin assignments, follow these steps:

  1. Make pin assignment changes directly in the I/O Designer software, or the software can automatically update changes made in a board layout tool that are back-annotated to a schematic entry program such as the DxDesigner software.
  2. To update the .fx with the changes, click Generate > FPGA Xchange File.
  3. Open your Intel® Quartus® Prime project.
  4. Click Assignments > Import Assignments.
  5. (Optional) To preserve original assignments before import, turn on Copy existing assignments into <project name>.qsf.bak before importing before importing the .fx.
  6. Select the .fx and click Open.
  7. Click OK.
