Hi,
LVDS IOs are simply set up by assigning LVDS IO standard to the (single ended) in- and output ports of LVDS IP or serdes implemented in HDL code. You have to select a pin that is specified as positive pin of a dedicated LVDS pair, the negative pin is then assigned automatically. Pin planner tool shows suitable pins or can select them automatically. The respective pin must use 2.5 V VCCIO.
