3.2.1. Dedicated Reference Clock Pins
Set the following assignments to the dedicated reference clock pins through the Assignment Editor of the Intel® Quartus® Prime Pro Edition software. Since the reference clock is a direct input to the Native PHY IP core and not an analog parameter you cannot set it through the GUI.
Use the XCVR_S10_REFCLK_TERM_TRISTATE QSF assignment to set the refclk tristate termination setting. All other assignments like INPUT_TERMINATION DIFFERENTIAL, XCVR_REFCLK_PIN_TERMINATION AC_COUPLING, XCVR_REFCLK_PIN_TERMINATION DC_COUPLING_EXTERNAL_RESISTOR, and XCVR_REFCLK_PIN_TERMINATION DC_COUPLING_INTERNAL_100_OHMS are for older device families and will be ignored when used for Intel® Stratix® 10 devices.
