摘要： A method of modeling electromagnetism in an irregular conductive plane, by dividing the surface into a grid of unequal and unaligned rectangles, assigning a circuit node location to a center of each rectangle, and calculating capacitive and inductive parameters based on the center circuit node locations. Rectangulation is accomplished using automated, recursive bisection. Capacitive segments are assigned to each circuit node and coincide with the corresponding rectangles. Inductive segments are assigned between adjacent rectangle pairs, with a width of an inductive segment defined as the common boundary of the corresponding pair of rectangles and the length of the inductive segment defined as the normal distance between circuit nodes of the two rectangles. Placement of the circuit nodes at the centers of the rectangles significantly reduces the number of nodes and segments, and provides a faster yet comprehensive analysis framework.

摘要： A method of simulating a circuit parameter such as voltage or current for a dominantly linear circuit by constructing a circuit equation matrix whose elements correspond to nodes of the circuit, decoupling linear and nonlinear contributions to the circuit parameter based on a partition of an inverse matrix of the circuit equation matrix, computing linear and nonlinear components using the decoupled contributions, and combining the nonlinear and linear components to yield a state of the circuit parameter for a given time step. The computation of the nonlinear component includes Newton-Raphson iterations to linearize nonlinear devices of the circuit, wherein the Newton-Raphson technique is applied to the right-hand side of the circuit state matrix equation. The computations are iteratively repeated for successive time steps which are advantageously separated by a constant time interval to avoid further recalculation of the state matrix.

摘要： Inductive effects in an integrated circuit device and/or system are modeled by partitioning the integrated circuit device and/or system into multiple windows or portions and determining a first localized inductance matrix for a first portion of the circuit and/or system and a second localized inductance matrix for a second portion of the circuit and/or system. The first and second localized inductance matrices are solved to obtain first and second localized susceptance vectors. The first and second localized susceptance vectors may be combined to form a susceptance matrix, which may be used directly in a susceptance-based simulator, or inverted to obtain a sparser inductance matrix that is representative of the inductive couplings in the entire integrated circuit device and/or system.

摘要： Systems, methods and computer program products create an equivalent circuit of electric and/or electronic circuit components, by identifying groups of components and hierarchically modeling aggregate interactions among the groups of components, to create increasingly higher level circuit models, until the equivalent circuit for the components is produced. Hierarchical modeling is provided by defining global components that reflect aggregate parameters of the groups of components and modeling the aggregate interaction among the groups of components as interactions among the global components. Moreover, next higher level global components also are defined that reflect aggregate parameters of at least some of the global components, and the aggregate interaction among the groups of components is modeled as interactions among the next higher level global components. The groups of components may be remote from one another and the hierarchical modeling includes hierarchical modeling of aggregate parasitic couplings among the groups of components.
