20.4.5.3. XCVR_ANALOG_SETTINGS_PROTOCOL

Pin Planner and Assignment Editor Name

Transceiver Analog Settings Protocol

Description

Specifies the protocol that a transceiver implements. When you use this setting for fully characterized devices, the Intel® Quartus® Prime software automatically sets the optimal values for analog settings, including the VOD, pre-emphasis, and slew rate. For devices that are not fully characterized, the Intel® Quartus® Prime software specifies these settings using preliminary data. If you assign a value to XCVR_ANALOG_SETTINGS_PROTOCOL, you cannot assign a value for any settings that this parameter controls. For example, for PCIe, the XCVR_ANALOG_SETTINGS_PROTOCOL assigns a value to XCVR_RX_BYPASS_EQ_STAGES_234. If you also assign a value to this parameter, a Intel® Quartus® Prime Fitter error results as shown in the following example:
