PROBLEM TO BE SOLVED: To provide a method for checking the wiring of a printed wiring board stably extracting nets regardless of the original data configuration, and also to provide a wiring check program for implementing the method.;SOLUTION: The wiring checking method includes: raster development processes (step S1-step S5, step S12) for causing raster development of artwork data onto the memory of a computer that constitutes a portion of a CAD system; centerline indexing processes (step S6-step S9) for selecting one figure element from images shown by the raster data obtained through the raster development and for indexing the centerline of the figure element; a pin recognition process for recognizing the end point coordinates of the indexed centerline as pins; and a connection relationship retrieval process (step S10) for retrieving the connection relationship between the pins recognized.;COPYRIGHT: (C)2005,JPO&NCIPI
