Abstract: Methods for routing in the design of integrated circuits (ICs) to simplify the routing task. The method includes dividing a given IC design into a limited number of non-overlapping tiles, and then routing all tiles in parallel, each tile being independently routed by a standard router. Thereafter, routed tiles are assembled to form a routing solution for the entire IC. Details of exemplary methods are disclosed.

Abstract: A method and system for generating designs by repetition of a user-defined image component which is arranged throughout an image pixelmap according to any desired pattern. Vector descriptions are used to specify pixelmap locations where the unit cell is to be copied. A user can define placement vectors that copy the unit cells apart from one another, adjacent one another or in an overlapping pattern. In the latter case, a formalism is provided for "masking out" a portion of the unit cell to avoid deletion of desired image information.
Abstract: A method and system for creating color separations comprising discrete computational objects whose edge contours are mutually compatible, such contours being defined based on user-selected n-way color relationships. The objects may be moved, copied, scaled, re-oriented, altered in appearance or resolution, or otherwise manipulated by a user as units. In operation, the invention analyzes a multicolored pixelmap to identify edges associated with regions of a particular color. As it traces an edge the invention generates a secondary edge whose distance from the original edge is determined by the pairwise relationship between the adjacent colors; that distance may vary as the color abutting the edge changes. The pixels along the secondary edge are stored as an order list of pixels that defines the object thus traced.
