1.9. P-Tile IP for PCI Express IP Cores v8.1.0

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, IPs have a new IP versioning scheme.

The IP version (X.Y.Z) number may change from one Quartus® Prime software version to another. A change in:
  • X indicates a major revision of the IP. If you update your 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.
Table 25.  v8.1.0 2022.06.20
Quartus® Prime Version Description Impact
22.2 Added support for new configurations of a single x8 port at Gen3 and Gen4 to the P-tile Avalon Streaming IP for PCI Express.

This IP can support one x8 interface in Endpoint mode only.

Only the PIO design example supports simulation and hardware testing for the 1x8 interface.

Fixed the functional issue with the p#_app_req_retry_en_i port of the P-tile Avalon Streaming IP for PCI Express. For applications that need to hold off on enumeration, use this port in Quartus Prime Pro from v22.2 onward.
