Wiring board design support apparatus, method for wiring board via arrangement and storage medium recording program for wiring board via arrangement

A method for wiring board via arrangement for arranging a plurality of vias on a wiring board, comprising:

• storing, by a design information storage unit, design information of vias and wirings to be arranged on the wiring board;
• and
• moving, by a wiring board via arrangement unit, on a basis of the design information, positions of lattice points arranged with same intervals in vertical and horizontal directions by a given moving amount in a vertical direction and a horizontal direction while alternately changing a moving direction in the horizontal direction of the lattice points for each row of the lattice and alternately changing a moving direction in the vertical direction of the lattice points for each column of the lattice, so as to arrange vias at positions of the lattice points after movement.

A recording medium readable by a computer storing a program for wiring board via arrangement, the computer comprising:

• a design information storage unit that stores design information of vias and wirings to be arranged on a wiring board;
• and
• a wiring board via arrangement unit that moves, on a basis of the design information, positions of lattice points arranged with same intervals in vertical and horizontal directions by a given moving amount in a vertical direction and a horizontal direction while alternately changing a moving direction in the horizontal direction of the lattice points for each row of the lattice and alternately changing a moving direction in the vertical direction of the lattice points for each column of the lattice, so as to arrange vias at positions of the lattice points after movement.
