IP versions are the same as the
Quartus® Prime Design Suite software versions up to v19.1. From
Quartus® Prime Design Suite software version 19.2 or later, IP cores
have a new IP versioning scheme.
The IP versioning scheme (X.Y.Z) number changes from one software
version to another. A change in:
X indicates a major revision of the IP. If you update your
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.
