<p><P>PROBLEM TO BE SOLVED: To improve convenience to a designer by intuitively representing an optimum size and position of an area where a line length is adjusted. <P>SOLUTION: A display example 1 show that the line length adjustment area of a wiring path is displayed near a wiring line group comprising the wiring path. (A) indicates an example of deriving the adjustment area from a line length restriction condition. A difference between a target line length and the line length is obtained for each wiring path, and it is used as an adjustment line length of each wiring path. Thereafter, the total adjustment line length is calculated. The total adjustment line length is applied to a line length adjustment area conversion function to obtain the area of the line length adjustment area. (B) indicates a state that the line length adjustment area corresponding to the area derived in (A) is drawn near the wiring line group. Thus, by displaying the line length adjustment area necessary for the wiring line group near the wiring line group, the area necessary to increase the line length of the wiring path constituting the wiring line group and to equalize the line length can be acquired. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
