  • Patent number: 7231618
    Abstract: An RLGC library is generated so as to include fringe RLCG functions for 2-D canonical interconnect structures. During parameter extraction for selected interconnect structures of an integrated circuit, printed circuit board, or integrated circuit package design, the RLGC library is used to generate fringe RLGC coefficients which in addition to area RLGC coefficients calculated on-the-fly, are used to generate equivalent RLGC circuits or S-parameters for simulating the interconnect structures.

  • Patent number: 7178125
    Abstract: A method for modeling a triangle meshed interconnect structure using an electrically equivalent three rectangle combination for each triangle in the triangle mesh is described. In the method, a surface of an interconnect structure is meshed with triangles. Three rectangles are then defined for each triangle so that each rectangle shares a different side of the triangle. Rectangle circuit models are determined so that the three rectangles are approximately equivalent electrically to the triangle when coupled together. The interconnect circuit model is then formed by connecting together the rectangle circuit models for all triangles defined on the surface of the interconnect structure.
