GMII to RMII Converter usage restrictions

Hi,

The GMII to RGMII converter core is supported in Arria 10 check this link https://www.intel.com/content/www/us/en/docs/programmable/683130/24-3/device-support.html

However, cannot use the GMII to RGMII Converter with the Triple-Speed Ethernet. Check internal message below:

Our internal team replied that RGMII is supported for our Arria 10 SoC HPS EMAC.

However, to use the Triple-Speed Ethernet IP, the RGMII interface is not supported in Intel Arria 10.

So the answer is no, you cannot use the HPS GMII to RGMII Converter with the Triple-Speed Ethernet, since the RGMII interface is not supported for Arria 10.

Check this KDB as well: https://www.intel.com/content/www/us/en/support/programmable/articles/000077033.html

Thanks,

Hi,

The timing fails only for RGMII with Triple Speed Ethernet. So the RGMII interface is not supported in Stratix® 10, Arria® 10, and Cyclone® 10 GX devices from Quartus® Prime software version 17.1 onwards check this link https://www.intel.com/content/www/us/en/docs/programmable/683402/24-3/core-configuration.html

There's no problem with the HPS IO.

Thanks,

Regards,
