摘要:
Method for detecting hotspots in a circuit layout includes constructing a layout graph having nodes, corner edges and proximity edges from the circuit layout, converting the layout graph to a corresponding dual graph, and iteratively selecting edges and nodes having weights greater than a predetermined threshold value at each iteration as hotspots.
