摘要:Roughly described, while manually dragging shapes during IC layout editing,editing operations determine which edges of which shapes are moving at what speed
ratios. Based on the edge information and the DRC rules, the system calculates andkeeps track of the minimum of the maximum distance the edges are allowed to movewith the cursor without violating DRC rules, in four linear directions and all cornerdirections. Once a next cursor destination point is known, a DRC clean destination point iscalculated based on the linear and corner bounds. If the next cursor position is beyond athe push-through distance ahead of the new DRC clean point, the editing objects aremoved to the user's destination point. Otherwise, the editing objects are moved to thenew DRC clean destination point, thereby stopping movement at that point.
