PROBLEM TO BE SOLVED: To read connection information of bundled lines and signal names constituting bundled lines in a short time by displaying bundled lines and pin pair in accordance with respective data of a list of bundled lines, a list of pin pairs, and aboard design. SOLUTION: A pin pair extraction part 11 generates a pin pair list 12 from pin position information and circuit connection information for each of parts stored in a board design data storage part 2. A bundled line detector 13 searches signal names in the pin pair list 12 to discriminates signal names taking a form of (bundle signal name) + (numerical value) as names of bundled lines and describes them in the list of bundled lines. A display control part 15 displays bundled lines in a range designated by an input device 3 as well as bundled lines and bundle signal names, which are based on parts information from the board design data storage part 2 and information in the list of bundled lines, on a display device 4. Bundled lines have a width corresponding to the number of bundled lines so that they can be distinctly distinguished from pin pairs, and their bundle signal name is displayed in the center of bundled lines. |
