<p>PROBLEM TO BE SOLVED: To solve a problem that if a full bond positioning is determined without determining a pad position in pad layout design of an LSI, as its flexibility is too high, a solution of satisfying simultaneously all restraint conditions is not necessarily acquired. SOLUTION: This optimal layout determiner 1 comprises: a parameter setting part 5; a pad layout boundary determination part 6; a pad layout recommendable region calculation part 7; a pad tentative position determination part 8; a bond arrangeable region calculation part 9; a bond tentative position determination part 10; a restraint sufficient evaluation part 11; and a parameter change part 12.</p> |
