CIRCUIT BOARD DESIGN AID APPARATUS, CIRCUIT BOARD DESIGN AID METHOD, AND COMPUTER-READABLE STORAGE MEDIUM STORTING CIRCUIT BOARD DESIGN AID PROGRAM

The present disclosure includes a basic shield pattern element generation section configured to generate a basic shield pattern element based on a geometry of the pattern element and a preset pattern generation condition; a prohibition region generation section configured to generate a prohibition region based on a geometry of an element for which a clearance check is to be performed located around the wiring pattern and a clearance condition between the element for performing a clearance check and the wiring pattern; and a shield pattern geometry generation section configured to generate the shield pattern by excluding the geometry of the prohibition region from a geometry of the basic shield pattern element, thereby improving the design efficiency and design quality by efficiently generating shield patterns even when an element for which a clearance check is to be performed is present in the vicinity of the wiring pattern.
