Dinamically change frequency eye scan - UltraSCALE+

Hello, we are trying to change the frequency of the transceiver channel dynamically (without reprogramming the FPGA). Ideally, we would not use Vivado to do this.Any thoughts on how to achieve this? 

Thanks,

Hi @pedroleaoc ,

it would depend between what line rates you want to switch. Would the functionality of TXRATE/RXRATE already be sufficient by just changing the output dividers?
Or would you need something completely different?
Then you would need to generate transceiver cores for each setup you want to support. And then you would need to compare the designs and transceiver attributes and you would need to add logic to switch between these setups and to change the different attributes through DRP.
