8.9.2. XCVR_A10_TX_XTX_PATH_ANALOG_MODE
Pin planner or Assignment Editor Name
Transmitter Analog Presets
Description
Specifies the TX pin swing settings such as vod output swing control, pre-emphasis
and slew rate settings for various protocols. The presets are set by selecting an
analog_mode setting. The selection is done as a .QSF setting on the TX pin. If
individual .QSF is specified for the vod_output_swing_ctrl, pre-emphasis settings, the
individual .QSF overrides the preset settings. The parameter defaults to
USER_CUSTOM, which requires the individual .QSF to be set. Available TX preset
values are shown in the Assignment Editor, Transmitter Analog Preset assignment
section.
8.10. Unused Transceiver RX Channels Settings
Add the following Intel Arria 10 QSF assignments to prevent performance degradation
of unused RX serial clock over time. You can either use a global assignment or per-pin
assignments.
