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 will override 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.

Add the following Intel Cyclone 10 GX QSF assignments for RX pins to prevent
performance degradation of unused receiver serial clocks over time. You can either
use a global assignment or per-pin assignments. For per-pin assignments, you can
specify a true or a complement RX pin.
