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.

A geometric description of the entire integrated circuit package is determined. The description is subdivided into non-uniform areas. A resistance of each one of the non-uniform areas is determined. A resistive netlist of the entire integrated circuit package is then determined by combining the resistance of each one of the non-uniform areas.

摘要： A method, an apparatus, and a computer program are provided to measure and/or correct duty cycles. Duty cycles of various signals, specifically clocking signals, are important. However, measurement of very high frequency signals, off-chip, and in a laboratory environment can be very difficult and present numerous problems. To combat problems associated with making off-chip measurements and adjustments of signal duty cycles, comparisons are made between input signals and divided input signals that allow for easy measurement and adjustment of on-chip signals, including clocking signals.

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 system and method for estimating propagation noise that is induced by a non-zero noise glitch at the input of the driver circuit. Such propagation noise is a function of both the input noise glitch and the driver output effective capacitive load, which is typically part of the total wiring capacitance due to resistive shielding in deep sub-micron interconnects. The noise-driven effective capacitance solution provided herein also estimates the propagation noise induced by a non-zero noise glitch at the input of the driving gate. Gate propagation noise rules describing a relationship between the output noise properties and the input noise properties and the output loading capacitance are used within the noise-driven effective capacitance process to determine the linear Thevenin model of the driving gate. The linearized Thevenin driver model is then employed to analyze both the propagation noise and the combined coupling and propagation noise typically seen in global signal nets.

摘要： The present invention relates to a method for analyzing the noise prediction within one or more electrical circuits, wherein the electrical circuits have a power mesh grid distribution system that feeds power levels to the electrical circuits that are connected by signal wires. After identifying a driver and receiver electrical circuit to be analyzed, a power block is generated that is associated with the driver and receiver electrical circuit by partitioning an area of a power mesh grid distribution system into a power block that can be modeled with lossy transmission line techniques. Next, signal wires situated between the driver and receiver electrical circuits are partitioned into signal blocks that can be modeled with lossy transmission line techniques. Lastly, the power blocks and signal blocks associated with the electrical circuits are analyzed in order to predict the noise performance within the electrical circuits.
