Abstract
Some embodiments of the invention are placers that use lines that are not orthogonal with each other to calculate the costs of potential placement configurations. Some of these embodiments use non-orthogonal lines to measure congestion costs of potential placement configurations. For instance, some embodiments use non-orthogonal lines as cut lines that divide the IC layout into regions. These embodiments then generate congestion-cost estimates by measuring the number of nets cut by the cut lines.
