Title:
DESIGN RULE VERIFICATION SYSTEM
Document Type and Number:
Japanese Patent JP2778483
Kind Code:
B2
Abstract:
PURPOSE: To fast verify the design rules among objects even when the object end points are shifted from each other by inputting jet the set data on the contact points set between the net outputted from an automatic layer system and the wiring segment path having the object kinds.
CONSTITUTION: The object data outputted from an automatic layout system 11 are inputted through an object data input means 12, sorted into the sets on each layer by an object data sorting means 13, and an adjacent object retrieving means 14 retrieves all pairs of object adjacent to each other on each layer. A contact rectangle inclusion deciding means 16 deletes such a pair of objects out of the retrieving subjects that have the same nets and also have the end points of the wiring segments included in the contact rectangle added by a contact rectangle forming means 15 among those pairs of adjacent objects.
