    摘要: Some embodiments of the invention provide a Local Preferred Direction (LPD) wiring model for use with one or more EDA tools. An LPD wiring model allows at least one wiring layer (200) to have a set of regions (205, 210, 215) that each has a different preferred direction (-45°, 0°, 90°) than the particular wiring layer. In addition, each region (205, 210, 215) has a local preferred direction (-45°, 0°, 90°) that differs from the local preferred direction of at least one other region in the set. Furthermore, at least two regions have two different polygonal shapes and no region in the set encompasses another region in the set. Some embodiments also provide a Graphical User Interface (GUI) that facilitates a visual presentation of an LPD design layout and provides tools to create and manipulate LPD regions in a design layout.
