1.15. P-Tile IP for PCI Express IP Cores v4.0.0
Quartus® Prime Version | Description | Impact |
---|---|---|
21.1 | The P-tile Avalon® Memory-mapped IP will not be supported in future releases of Quartus® Prime. | The P-tile Avalon® Memory-mapped IP will not be available in the IP Catalog in future releases of Quartus® Prime. The replacement IP is the MCDMA-based PCIe Avalon® Memory-mapped IP. |
The IP version of the P-tile Avalon® Streaming IP is the same in the 21.1 release and 20.4 release. However, the IP needs to be regenerated when migrating from 20.4 to 21.1. | Regenerating the P-tile Avalon® Streaming IP when migrating from 20.4 to 21.1 allows you to take advantage of the 21.1 IP bug fixes and enhancements. | |
The following note was removed from the P-tile Avalon® Streaming IP for PCI Express* User Guide:
Note: If VirtIO is enabled, the CII is used for VirtIO transport and is not available to the application logic for other purposes.
|
In 21.1, when VirtIO is enabled, Configuration accesses to the PF/VF VirtIO Capability register range and certain PF/VF PCIe Capability register ranges are not visible to the Configuration Intercept Interface (CII) and can still be issued by the application logic. Refer to the P-tile Avalon® Streaming IP for PCI Express* User Guide for more details. | |
The design implementation for the VirtIO feature of the P-tile Avalon® Streaming IP has been improved. | Resource utilization has been reduced for the P-tile Avalon® Streaming IP when VirtIO is enabled. | |
The unconstrained clocks issue in the P-tile Avalon® Streaming IP has been fixed. | This fix allows you to run a comprehensive timing analysis with all the required clocks constrained on this IP. | |
Critical timing paths have been optimized for the P-tile Avalon® Streaming IP. The timing closure issue when VirtIO is enabled has also been addressed in this release. | Timing margins have been improved for the P-tile Avalon® Streaming IP. | |
The 2048 VFs issue when VirtIO is enabled in the P-tile Avalon® Streaming IP has been addressed. | In 21.1, you can enable all 2048 VFs when VirtIO is enabled. | |
The P-tile Avalon® Memory-mapped IP does not export the legacy interrupt pin (intx_req_i) when the Enable Legacy Interrupts option is enabled in the IP Parameter Editor. | The P-tile Avalon® Memory-mapped IP does not support legacy interrupts in this release. Use MSI or MSI-X instead for interrupts. |
