ABSTRACT:
In a wire length minimization apparatus for moving an object and a wire in a wiring pattern formed by connecting objects with wires, in accordance with a load representing a performance of wire length minimization considering a priority set for each wire, thereby minimizing a length of the wire, a tree having, as nodes, a plurality of objects having a predetermined positional relationship are formed, a load of a parent node with respect to a child node is calculated sequentially from a leaf of the tree based on a load of the child node, and an object and a wire corresponding to a tree portion having a root node with a load satisfying a predetermined condition is satisfied as an object to be moved. With this arrangement, movement of the objects and wires can be executed to efficiently and effectively reduce the cost of the wires.
