6.1. Release Information for IOPLL Reconfig Intel® FPGA IP

Intel® FPGA IP versions match the Intel® Quartus® Prime Design Suite software versions until v19.1. Starting in Intel® Quartus® Prime Design Suite software version 19.2, Intel® FPGA IP has a new versioning scheme.

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.
