摘要： Disclosed is a method, system, and computer program product for routing, modeling routes, and measuring congestion. In some embodiments, Gcells are implemented with reduced number of nodes to facilitate route modeling and congestion measurement. Some embodiments are particularly suitable for direct congestion and routing analysis of diagonal routing paths. In this way, congestion analysis can be directly performed along diagonal boundaries for diagonal routes, without requiring association with Gcell boundaries on Manhattan routing layers.

摘要： Some embodiments of the invention provide a method for routing. The method defines at least one wiring layer that has at least two regions with different local preferred wiring directions. The method then uses the differing local preferred wiring directions to define a global route on the wiring layer. The two regions are a first region with a first local preferred wiring direction, and a second region with a second local preferred wiring direction. The global route traverses the first region along the first local preferred wiring direction and traverses the second region along the second local preferred wiring direction.

摘要： Some embodiments of the invention provide a method for defining wiring directions in a design layout having several wiring layers. The method decomposes a first wiring layer into several non-overlapping regions. It assigns at least two different local preferred wiring directions to at least two of the regions. In some embodiment, the method decomposing the first wiring layer by using the vertices of items in the layout to decompose the layout. In some of these embodiments, the item include macro blocks. The method of some embodiments also identifies several power via arrays on the first wiring layer, and identifies a local preferred wiring direction based on the arrangement of the power via arrays on the first wiring layer.
