1.5. P-Tile IP for PCI Express IP Cores v6.0.0

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, IPs have a new IP versioning scheme.

The IP version (X.Y.Z) number may change from one Intel® Quartus® Prime 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.
Table 13.  v6.0.0 2021.10.04
Intel® Quartus® Prime Version Description Impact
21.3

The following signals are added to the Power Management Interface:

sys_aux_pwr_det_i

apps_ready_entr_l23_i

apps_pm_xmt_turnoff_i

app_xfer_pending_i

User application is required to accommodate the new signals for the Power Management Interface. Upgrade to Intel® Quartus® Prime Pro Edition v21.3 if Power Management support is required.
Added support for Gen4 x8/x8 512-bit configuration. The data bus width increase allows better performance.
Added support for Gen3 x16 256-bit configuration. The new data bus width provides timing closure flexibility.
The P-tile Avalon® Streaming and Avalon® Memory-mapped IPs for PCIe do not support parallel PIPE simulations. There is no plan to add support for parallel PIPE simulations.

The Power Management behavior of P-tile IPs for PCIe was updated to align with the behavior of the IPs for other tiles.

L2/L3 entry Ok Ok
L2 exit Host to initiate or Cold Reset Cold Reset
L3 exit Cold Reset Cold Reset
The Power Management behavior is now aligned for IPs for PCIe across P/F/R-tiles.
Added support to enable ECRC and LCRC error counters. Improved error telemetry capabilities by allowing the counting of ECRC and LCRC errors on a PCIe link.
