Using 1G/2.5G Ethernet PCS/PMA as SGMII to GMII Bridge on KC705 board

[chintala]

Hi,

I want to use "1G/2.5G Ethernet PCS/PMA" IP core as "SGMII to GMII Bridge" on KC705 board.

The scenario is like this

MAC <=> SGMII-GMII bridge <=> CPRI [PHY] <=> SFP <=> optical fiber

What should be the configuration of the core?

Even if you dont know the exact answer, please help me in whatever way you can. 

Thanks

Hi @chintala 

Can you please clarify whether the MAC in your design flow is from Xilinx or is it your custom IP. 

[chintala]

It is not from Xilinx. It sits outside the FPGA and communicates through SGMII interface.

Just generate 1G PCSPMA IP core with the interface "GMII" selected?

[chintala]

I am not able to see that option when configuring the 1G/2.5G PCS,PMA or SGMI core. 

How to generate with GMII interface?

[guozhenp]

Sorry, I mistook it.

SGMII IP core just use the GMII interface.

Hi,
when you choose SGMII, a bridge will be generated
and there is not GMII interface in this IP core, GMII is on tri_mode_ethernet IP CORE
