Hi, In ARTIX7 GTP the TX FSM under init module is stuck inactive. PHALIGNMENT_DONE is not asserted and the TxFSMrESETdone is stuck at low. I introducded this issue when I tried to bypass TXBUFFER and RXBUFFER . Also I tried to Modify the constants/ counter value in the tx_Startup_fsm according to the stable clock period and still no luck.

does TXRESETDONE or RXRESETDONE go high?
did you try example design?
