I think he means LVS as in Logic vs Schematic - a form of layout checking commonly found in ASIC design, not LVDS as in Low-Voltage Differential Signaling. In the ASIC world, LVS is a fairly complex problem that usually involves re-creating the netlist from the layout, then comparing that to the original netlist. This requires fairly detailed understanding of device structures to infer higher-level functionality. For PCB it may be more trivial, since all that need be re-created is the netlist itself, not the devices. Nonetheless it's not simple.
