Agilex Ftile is not asserting tx_ready after the reset sequence (tx_rreset/tx_reset_ack)

Hello, I build my controller model to Agilex F-tile transceiver. Please see the configuration below for F-tile and simulation waveform. Xcvr is asserting tx_reset/tx_reset_ack and rx_reset/rx_r...

Hi,


Are you getting tx_reset_ack and rx_reset_ack?


tx_ready will assert when TX PMA and TX datapath are reset successfully and ready for data transfer.


and rx_ready will assert when RX PMA and RX datapath are reset successfully and ready for data transfer, If RX de-skew is disabled.


Note: During F-Tile link initialization, the data pattern sent from the TX has to be scrambled to get rx_ready to assert. If a 0101 pattern or other constant patterns are sent, rx_ready does not assert, and the link does not initialize.


tx_ready and rx_ready will assert when reset has been done successfully.


Thank you
