A timing constraint generating support apparatus includes a propagation unit that propagates, through a wire connecting the logic circuits, timing constraints set for the logic circuits by using circuit information that represents information relating to the logic circuits and connection information that represents information of the wire, a determination unit that determines whether or not a plurality of timing constraints different from each other are propagated through the wire by the propagation unit, and an output unit that outputs information representing that the timing constraints propagated through the wire overlap each other in a case where the plurality of timing constraints different from each other are determined to be propagated through the wire by the determination unit.
