摘要： Methods and apparatus are provided for predicting the number of iterations needed for a computed Transversal Waveform Relaxation solution to achieve a given level of accuracy. In this manner, a Transversal Waveform Relaxation algorithm is disclosed that provides full automation. According to one aspect of the invention, a circuit is analyzed having transmission lines. One or more transmission line parameters of the circuit are obtained, as well as the intrinsic behavior, E(ω), and strength of coupling, N(ω), of each of the transmission lines. In addition, a relative error bound is obtained for the circuit based on the intrinsic behavior, E(ω), and strength of coupling, N(ω), of the transmission lines and a predefined error threshold. The process then iterates until the relative error bound satisfies the error threshold.

摘要： A method for fabricating a transceiver, which simultaneously provides impedance matched transmission for radio frequency (RF) and shields against transmission losses due to parasitic effects includes identifying parasitic electromagnetic elements associated with an RF choke for a given placement on a substrate. RF lines are placed and dimensioned on the bench to form impedance matched RF lines wherein a portion of the RF lines shield the RF choke for a given bandwidth such that impedance matching and control of parasitic effects of the RF choke are simultaneously provided wherein an intermediate capacitance formed between the RF choke and the shield is sized to balance against the parasitic effects to provide a desired transmission response over a selected frequency range.

摘要： A system and method for analyzing a circuit with transmission lines includes determining which sources influence each of a plurality of transmission lines, based on coupling factors. Transmission line parameters are computed based on the sources, which influence each transmission line. A transient response or frequency response is analyzed for each transmission line by segmenting each line to perform an analysis on that line. The step of analyzing is repeated using waveforms determined in a previous iteration until convergence to a resultant waveform has occurred.

摘要： The present invention is a method and apparatus for electrically decoupling conductors used to distribute power and ground potentials in electronic packages and chips. Specifically, the present invention utilizes Absorbing Plane Terminators (APTs), which are coupled between ground and power conductors of the electronic package. An APT includes a resistor with a value preferably chosen to match the approximate characteristic impedance of the conductor structures, and a decoupling capacitor connected in series with the resistor. The APT reduces electronic noise and electromagnetic radiation in electronic packages over a wide range of frequencies. The APT also dampens resonances caused by the parasitic inductance of the decoupling capacitor.

摘要： A model for modeling electromagnetic response in a conductor and in dielectric, a method of modeling the electromagnetic response in the conductor and dielectric and a program product therefor. Coupled supplies (delayed capacitive-current-controlled current sources or delayed inductance-voltage-controlled voltage sources) are low pass filtered in an electromagnetic model for the particular medium, e.g., a Partial Element Equivalent Circuit (PEEC) model for a conductor or dielectric. Thus, high frequency model instabilities are substantially reduced or eliminated.
