•Both reset and gt_reset inputs are active-High. Make sure the reset polarity is taken care in the hardware.
•Make sure the refclk frequency is exactly the same as the Aurora 8B/10B core is generated for.
•If the refclk is driven from a synthesizer, make sure the synthesizer is stable (locked).
•Make sure the cable connection from TXP/TXN to RXP/RXN is proper.
•If there are RXNOTINTABLE errors observed from the serial transceiver, validate the link using IBERT. Make sure there is no BER in the channel. Use the sweep test in the IBERT tool and use the same serial transceiver attributes which provide "Zero" BER in IBERT.
•A burst of soft errors results in a hard error and re-initializes the channel. Set ENABLE_SOFT_ERR_MONITOR to 0 in the <component name>_err_detect module to disable hard error assertion from soft errors.
