    摘要： A connector has data signal conductors for communicating data signals and voltage reference (power and ground) conductors for the signals' return currents. Voltage reference conductors carrying the same voltage level are coupled together at one or more points between the ends of the connector to shift the connector's resonant frequency beyond an operating frequency range of the data signals. Decoupling capacitors may alternatively or additionally be inserted between pairs of voltage reference conductors carrying high and low voltage levels at one or more points between the ends of the connector to shift the connector's resonant frequency beyond an operating frequency range of the data signals.

    摘要： 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.

    摘要： The present invention relates to an improved method for computer-aided electrical circuit simulation which combines circuit partitioning, modified nodal formulation and conjugate-gradient solution method to efficiently analyze large electrical circuit networks. Circuit partitioning is used to create sub-circuits which isolate the passive elements of the electrical circuit. Modified nodal formulation is used to formulate matrices representative of the resultant sub-circuits. All matrices resulting from the sub-circuits containing only passive elements will be positive-definite symmetric and are efficiently solved using conjugate gradient method. Conjugate-gradient method is known to be an extremely efficient method for solving matrices of this type.

    摘要： 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.

    摘要： A technique for determining performance characteristics of electronic systems is disclosed. In one exemplary embodiment, the technique may be realized as a method for determining performance characteristics of electronic systems. The method includes the steps of measuring a first response on a transmission medium from a falling edge transmitted on the transmission medium, and measuring a second response on the transmission medium from a rising edge transmitted on the transmission medium. The method also includes the step of determining worst case bit patterns for transmission on the transmission medium based upon the first response and the second response.
