Method, system, and computer program product to implement snapping for an electronic design

Abstract:

Disclosed is an approach to implement snapping techniques that aid the interactive, assisted, or automatic placement of layout instances or groups of layout instances for generating a legal placement layout while reducing or entirely eliminating any subsequent or separate performance of design rule checking with respect to the relevant design rules, constraints, or requirements governing the legality of the instances or groups of instances placed in the placement layout.
