Agilex 7 editing BTS transceiver example

Hi,

I have Agilex™ 7 FPGA I-Series Transceiver-SoC Development Kit that i want to use to transmit an PRBS9 pattern at 56G NRZ. Then on the receiver side i want to be Able to calculate the Bit error rate to judge the quality of the link.

I noticed the BTS GUI comes with some xcvr example for 56Gbps pam4, 100Gbps pam4 and 25Gbps NRZ. There is no 56Gbps NRZ examples. I tried to modifying the 100Gbps xcvr example and to make it run at 56Gbps NRZ however when I try to load the newly compiled sof with BTS GUI i get the following warning.

"The design running on device is incompatible with related design within image folder"

I have a lot of SerDes experience but i am new working with FPGAs.

1. Is there another example that i can follow to create 56Gbps NRZ transimitter or receiver? With GUI similar to the BTS.

2. Is modifying a BTS example even an option? Or are the BTS examples just fixed and cannot be edited.

Would greatly appreciate any guidance on whats the right approach for this task.

Thanks
