Does AXI Manager support RGMII

Hello,

I want to accelerate the data transmission between PC and FPGA, by replace JTAG by PLEthernet. However, my FPGA only has RGMII Ethernet Interfaces and the RGMII IP is not supported. Does axi manager support RGMII PLEthernet? Or can I use third party UDP stack?

In this page, it is confusing whether the RGMII interface is supported.

Looking forward to your reply.

Hi KH,

If I understood the query correctly you want to know if the AXI manager supports RGMII interface. Based on the documentation (https://in.mathworks.com/help/hdlverifier/ug/new-fpga-board-wizard-reference.html#buqnn9v), RGMII is mentioned as a supported interface for FIL (Gigabit Ethernet, Altera Boards).

However, for FPGA data capture and AXI manager, only GMII, MII, and SGMII interfaces are explicitly supported, as stated in the documentation.

Since your FPGA only has an RGMII interface and AXI manager does not officially support it, you may need to consider alternative approaches like using an RGMII-to-GMII bridge or third party ethernet stack.

Hope this helps!
