摘要： A design system for designing complex integrated circuits (ICs), a method of IC design and program product therefor. A layout unit receives a circuit description representing portions in a grid and glyph format. A checking unit checks grid and glyph portions of the design. An elaboration unit generates a target layout from the checked design. A data prep unit prepares the target layout for mask making. A pattern caching unit selectively replaces portions of the design with previously cached results for improved design efficiency.

摘要： A method for hierarchical very large scale integration design comprises representing a structure of the hierarchical very large scale integrated design as a graph comprising design objects. The method further comprises specifying a transformation behavior applied to the design objects, and processing, top-down, the graph to perform the transformation on the hierarchical very large scale integrated design.

摘要： Techniques for improving efficiency and accuracy of computer-aided design are provided. In one aspect, a method for generating a computer-based representation of a design having one or more shapes is provided comprising the following steps. Each of the shapes in the design is represented with one or more trapezoids, wherein a fixed number of non-vertical lines are used to define an x-coordinate of a left and right base and sides of each trapezoid with intersection points being formed between the non-vertical lines that define the sides. The x-coordinates and intersection points are used to divide the trapezoids into disjoint trapezoids, wherein each disjoint trapezoid is defined by a combination of the same non-vertical lines that are used to define one or more of the trapezoids. An order is assigned to the x-coordinates and intersection points, wherein the x-coordinates and intersection points in the assigned order are representative of the design.

摘要： An apparatus for serializing concurrent requests to multiple processors includes a signal merging tree structure and a traversal mechanism. The tree structure has a root node and leaf nodes for connecting a data consumer to the root. The tree structure serializes concurrent requests in the presence of race conditions, and connects each request producer from among the processors to a respective leaf node. The mechanism enables a producer to transmit a signal from a corresponding leaf node to the consumer at the root node by setting all nodes on a path from the leaf node to the root node to a Boolean true. The mechanism enables the consumer to trace signal submissions of the producers such that submission traversals by the producers and trace traversals by the consumer can be concurrently performed to allow data races between signal submissions by producers and between signal submissions by producers and the consumer.
