PROBLEM TO BE SOLVED: To attain improvement in design quality and reduction in design period in hierarchical design layout by determining an optimum terminal position.;SOLUTION: In the hierarchical design layout device 200, an acquisition part 201 acquires a first net list 211, and an extraction part 202 extracts a second net list 211 from the first net list 211. A floor plan execution part 203 executes floor planning. A temporary arrangement processing execution part 204 executes temporary arrangement processing. A setting part 205 sets a wiring prohibition area. A CTS processing part 206 performs CTS processing. A temporary wiring execution part 207 executes temporary wiring processing. A temporary determination part 208 temporarily determines a terminal position. An optimization processing part 209 executes optimization processing for the terminal position. A hierarchical layout part 210 carries out layout processing of high-order layers as well as layout processing of each low-order layer block.;COPYRIGHT: (C)2008,JPO&INPIT
