1.12. P-Tile IP for PCI Express IP Cores v1.1.0

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 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.
Table 44.  v1.1.0 2019.12.16
Intel® Quartus® Prime Version Description Impact
19.4 The VirtIO feature still has timing issues in this release of Intel® Quartus® Prime. Only compilation and simulation are supported for the VirtIO feature in this release.
An SR-IOV design example has been added for the P-Tile Avalon-ST IP for PCIe. This design example supports Gen3 x16 and Gen4 x16 Endpoint configurations.
No P-Tile IP upgrade is supported in the 19.4 release of Intel® Quartus® Prime. Users cannot upgrade a 19.3 P-Tile Avalon-ST or Avalon-MM IP to a 19.4 version.
The P-Tile Avalon-MM IP for PCIe does not support design example simulation in this release. The P-Tile Avalon-MM IP for PCIe may support design example simulation in a future release of Intel® Quartus® Prime.
A high-bandwidth Adapter has been introduced for the P-Tile Avalon Streaming IP. This Adapter allows the application logic to run Gen4 x8 and Gen4 x4 configurations with an application clock frequency of 250 MHz by doubling the Avalon Streaming data bus width. The Adapter is enabled automatically by Intel® Quartus® Prime when either the 512-bit Gen4 x8 or 256-bit Gen4 x4 configuration is selected.
The P-Tile Avalon Streaming IP for PCI Express does not support parity protection for the RX and TX Avalon Streaming interfaces in this release of Intel® Quartus® Prime. Parity protection for the RX and TX Avalon Streaming interfaces will be supported in a future release of Intel® Quartus® Prime.
