Low Latency Ethernet 10G MAC Intel FPGA IP Release Notes
RN-1122 | 2019.07.01
Low Latency Ethernet 10G MAC Intel FPGA IP Release Notes
If a release note is not available for a specific IP version, the IP has no changes in that version. For information on IP update releases up to v18.1, refer to the Intel® Quartus® Prime Design Suite Update Release Notes.
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, IP cores 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.

These changes are optional. If you do not upgrade your IP core, it does not have these new features. |
| You cannot turn on the Enable ECC on memory blocks parameter with the Enable time stamping parameter. | The IP core may not exhibit the expected behavior when both parameters are turned on at the same time. This is applicable in Intel® Quartus® Prime Pro Edition and Intel® Quartus® Prime Standard Edition version 17.0 and earlier. |
Design Examples for Low Latency 10G Ethernet
MAC:

|
In previous versions of the Low Latency Ethernet 10G MAC design example for Intel® Arria® 10 devices, the IOPLL and transceiver PLL output may experience additional jitter. The additional jitter occurs if you source the reference clock from a cascaded PLL output, global clock, or core clock. To compensate for the jitter, the designs require additional constraints. This issue has been fixed in Intel® Quartus® Prime version 17.1. |
If you are upgrading designs that have these additional constraints from the previous versions of Intel® Quartus® Prime to version 17.1, you must revise the constraints. Refer to the KDB page for more information. |
| 10GBASE-R register mode is not supported in Intel® Stratix® 10 devices. | — |
