  • Patent number: 7225423
    Abstract: A system and method for designing ICs, including the steps of: analyzing and optimizing a target IC design based on design-specific objectives; partitioning the optimized target IC design into pre-defined standard-cells from one or more libraries and creating design-specific cells specifically having unique functionality and characteristics not found amongst the standard-cells; identifying and determining a minimal subset of the standard-cells and design-specific cells, the interconnection of which represents the target IC design; generating the necessary views, including layout and characterizing of the design-specific cells included in a unique, minimal subset, wherein the IC design is subject to objectives and constraints of the target IC.

  • Patent number: 7003738
    Abstract: The present invention pertains to an automated method for designing a integrated circuit (IC) design-specific cell, the method includes the steps of receiving a design specification for the design-specific cell, mapping a transistor-level representation of the design-specific cell, wherein the mapping is based on at least one, but perhaps plural design specifications, and evaluating the transistor-level representation of the design-specific cell for satisfaction of the design specification.

  • Patent number: 6938223
    Abstract: A method and system for constructing, designing, and using a family of logic circuits based on methods of interconnecting transistors (or more generally, switches). The method includes the selective use of functionally redundant transistors to achieve target objectives, such as speed of operation, power dissipation, control over switching capacitances, noise characteristics and signal integrity. In accordance with the present invention, multiple topologies may be incorporated into the implementation of a single dynamic transistor topology. The logic circuit family provides flexibility by implementing different topologies for the various functionally redundant sub-networks of transistors. The method is applicable to any network of transistors whose characteristics depend, at least in part, on its implementation topology.

  • Patent number: 6782514
    Abstract: The present invention relates to a method for minimizing the number of standard cells required to implement a digital circuit and for improving the characterization of new standard cells based on their context/environment. In addition, a systematic method that utilizes detailed characterization at the transistor-level on critical areas of the design for improved characterization and optimization of the entire design is presented.
