Abstract
A board design aid device includes a calculating and correcting units. The calculating unit groups a plurality of layers in a multi-layer board into a plurality of pairs of layers based on design information of the multi-layer board, the plurality of layers being stacked and derives a difference of total amounts in respect to a board design element, each of the total amounts being related to each layer of a pair of layers of the plurality of pairs of layers, the board design element being related to a warp of the multi-layer board. The correcting units, based on the difference of the total amounts, corrects an amount of the board design element for at least one of layers among at least one of the plurality of the pairs of layers so that the difference of the total amounts of the board design element is maintained within a certain range.
