Even un-invoked power pins with matching names (Vdd, Vcc, Gnd, Vss, etc) should appear on the board as airwires. If there aren't any airwires on the board at all for the power pins, you may have a different problem. (unless you were unlucky enough to have different power net names for each chip on your design, and no power net with the same name anywhere else in your design...)
