IP versions are the same as the Intel® Quartus® Prime Design Suite software versions up to v19.1. From Intel® Quartus® Prime Design Suite software version 19.2 or later, IP cores have a new IP versioning scheme.

If an IP core version is not listed, the user guide for the previous IP core version applies.
