2.2.2.1.1. Limitations on the Preserved Nios® II Processor in Quartus® Prime Pro Edition version 24.1 and Newer

In QIP approach, opening Nios® II processor projects in Quartus® Prime Pro Edition version 24.1 and newer has one limitation; you cannot upgrade the project using IP Upgrade.
Figure 18. IP Upgrade Window
Due to the inability to upgrade the IP in Quartus® Prime Pro Edition version 24.1 and newer, the following limitations occur:
  • You cannot upgrade or change the Nios® II processor system, such as switching a Nios® II/e processor to a Nios® II/f processor.
  • You cannot add, remove, or upgrade the soft IP peripherals to what was generated in the Platform Designer system. The IP version of soft IP peripherals is limited from Quartus_1.
  • You cannot change the system address map.
  • Any peripherals or systems that connect to the processor must remain unchanged in Quartus_2. This includes the Clock Bridge, Reset Bridge, and PLL IP Core.

You must revert the older Quartus® Prime Pro Edition software (Quartus_1) to make any changes to the processor system and regenerate the project HDL.
