GTP Manual Phase alignment

[appubaje]

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.

hi

does TXRESETDONE or RXRESETDONE go high?

did you try example design?

TXresetdone and RXresetdone are fine in hardware and I haven't done the simulation yet will try that.
