I am using XCZU19EGFFVD1760 FPGA board, and I am checking the 25G Ethernet Speed on Zynq UltraScale+ board with QSFP but GTY transceiver is not working.
In 10G/25G Ethernet Subsytem IP, I have set the GT selection and configuration according to the documents.
What could be the problem ? Anyone can suggest please
Speed : 25G
Enabled : 4 Cores
GT Selection and Configuration : GTY , Clock : 322.265 MHZ.

Is this for simulation?
Please try IP core example design first.
And add "-d SIM_SPEED_UP" to speed up the simulation
Can you see data in simulation?

Still you can try IP core example design with near end loopback mode first.
You can also run IBERT first to confirm that GTY HW environment is good.

Hi @thaus_015 ,
Also, please refer to page 20 for further detail of IBERT example design in https://www.xilinx.com/support/documentation/ip_documentation/ibert_ultrascale_gty/v1_3/pg196-ibert-ultrascale-gty.pdf.
