Hi,

XCVR_REFCLK_PIN_TERMINATION is ignored because this setting is no longer applicable to Arria 10 Device.

For Arria 10 XCVR, the correct XCVR refclk setting is XCVR_A10_REFCLK_TERM_TRISTATE. The setting can accept 2 value.

XCVR_S10_REFCLK_TERM_TRISTATE TRISTATE_OFF is used for AC coupled reference clock inputs

XCVR_S10_REFCLK_TERM_TRISTATE TRISTATE_ON is used for DC coupled reference clock inputs

You can always refer to Arria 10 Transceiver PHY User Guide doc to find out more on the correct setting implementation.
