Generated the GTY Transceiver Example design. Tried to simulate the example design(PMA Loopback) in vivado
simulator vivado 2018.1. i can see the mismatch in the received rx data with tx data. i have attached the
screenshot of GTY Preset and simulation waveform. please help me to resolve the issue.
TX Data = 32'ha7ed0409
RX Data = 32'h4fda0813
Here received rx data is shifted data of tx data. For reference, marked in the screenshot.
Device : Xilinx XCVU9P-2FSGD2104E Virtex UltraScale +
Tool : Vivado 2018.1

the data shift is expected. You have some latency in the transceiver that you cannot avoid.
