  • Publication number: 20060036977
    Abstract: 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.

  • Publication number: 20050086628
    Abstract: A method for analyzing circuit designs includes discretizing a design representation into pixel elements representative of a structure in the design and determining at least one property for each pixel element representing a portion of the design. Then, a response of the design is determined due to local properties across the design.
