1.7. P-Tile IP for PCI Express IP Cores v4.0.0

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.

Intel® Quartus® Prime Version Description Impact
20.4 Migrating a design using a P-tile Avalon® Streaming or Avalon® Memory-mapped IP from an earlier Intel® Quartus® Prime version to the 20.4 version requires an IP upgrade. You must regenerate any design using a P-tile Avalon® Streaming or Avalon® Memory-mapped IP when moving from an earlier Intel® Quartus® Prime version to the 20.4 version.
Parameters to enable independent resets for the ports in the bifurcated x8x8 Endpoint mode have been added to the IP Parameter Editor of the P-tile Avalon® Streaming and Avalon® Memory-mapped IPs. Each port in the bifurcated x8x8 Endpoint mode can be reset independently of the other port. Two new reset signals (p0_pld_clrpcs_n, p1_pld_clrpcs_n) are exported to the top-level block symbol when independent resets are enabled. These signals can be assigned to GPIO pins. Contact your local Field Applications Engineer (FAE) for more details.
The parameter to enable the MSI-X capability has been removed from the IP Parameter Editor when the P-tile Avalon® Streaming or Avalon® Memory-mapped IP is in Root Port (RP) mode. The P-tile Avalon® Streaming or Avalon® Memory-mapped IP is not required to support sending MSI-X in RP mode.
The parameter to enable extended tag support has been added to the IP Parameter Editor of the P-tile Avalon Streaming IP. The P-tile Avalon® Streaming IP can support extended tag in this release.
Options to set acceptable Power Management latencies for Endpoints were added to the IP Parameter Editor of the P-tile Avalon® Memory-mapped IP. L0s and L1s acceptable latencies can now be configured in the IP Parameter Editor of the P-tile Avalon® Memory-mapped IP in Endpoint mode.
Options to configure the VSEC parameters in Endpoint mode were added to the IP Parameter Editor of the P-tile Avalon® Memory-mapped IP. VSEC parameters can now be configured in the IP Parameter Editor of the P-tile Avalon® Memory-mapped IP in Endpoint mode.
The parameter to enable VirtIO and SR-IOV capabilities have been removed from the IP Parameter Editor when the P-tile Avalon® Streaming IP is in Root Port (RP) mode. The P-tile Avalon® Streaming IP is not required to support VirtIO or SR-IOV in RP mode.
Options for BAR configuration, Multi-function and SR-IOV support have been removed from the IP Parameter Editor when the P-tile Avalon® Streaming IP is in TLP Bypass mode. The P-tile Avalon® Streaming IP is not required to support these features in TLP Bypass mode.
Options for Multi-function and SR-IOV support support are now visible for Port 1 when the P-tile Avalon® Streaming IP is in a bifurcated mode. Multi-function and SR-IOV support can be enabled for Port 1 when the P-tile Avalon® Streaming IP is in a bifurcated mode.
The IP Parameter Editor response time has been improved for the P-tile Avalon® Streaming IP. The turnaround time after each user input in the IP Parameter Editor is significantly reduced for the P-tile Avalon® Streaming IP in this release.
