2.2.2.1. Handling Hardware Component in the Quartus® Prime Pro Edition Project

Ensure that the Nios® II project works successfully as a Quartus_1 project.
  1. Start Quartus_1 software and follow these steps:
    1. Open the Nios® II Quartus® Prime project.
    2. Verify that the QIP file is added into Project Navigator > Files.
    3. Verify that the QSYS file is removed from Project Navigator > Files.

  2. Start Quartus_2 software and follow these steps:
    1. Open the same Nios® II Quartus® Prime project.
    2. Ignore the recommended IP Upgrade.
    3. Do not perform Generate HDL.
    4. Proceed to compile the design in Quartus_2 software without regenerating HDL.

You have successfully migrated the discontinued Nios® II processor to a newer Quartus® Prime software (Quartus_2). Proceed to configure the design .SOF file into the FPGA devices.
