  • Distributed capacitance estimations of interconnects within integrated circuits
    Patent number: 5923568
    Abstract: A method of estimating the distributed capacitance of an interconnection line within an integrated circuit. The invention includes a method for estimating distributed capacitance between interconnection lines within an integrated circuit. The integrated circuit is modeled as including a middle plane which is planar and adjacent to a top plane and a bottom plane. Each plane includes a plurality of interconnection lines which are infinite in length and parallel. The interconnection lines of the middle plane are orthogonal to the interconnection lines of the top plane and the interconnection lines of the bottom plane. A ground plane is adjacent and planar to the bottom plane. A first value of capacitance between an interconnection line of the middle plane and an interconnection line of the top plane is estimated ignoring the effects of the bottom plane.
