Nios® V Processor Intel® FPGA IP Release Notes

The Intel® FPGA IP version (X.Y.Z) number can change with each Intel Quartus® Prime software version. A change in:

• X indicates a major revision of the IP. If you update the Intel Quartus Prime software, you must regenerate the IP.
• Y indicates the IP includes new features. Regenerate your IP to include these new features.
• Z indicates the IP includes minor changes. Regenerate your IP to include these changes.
