Systematic development of transmission-line models for interconnects with frequency-dependent losses
IEEE Transactions on Microwave Theory and Techniques, 2001
This paper presents a new method for the extraction of the frequency-dependent, per-unit-length (p.u.l.) resistance, and inductance parameters of multiconductor interconnects. The proposed extraction methodology is based on a new formulation of the magneto-quasi-static problem that allows lossy ground planes of finite thickness to be modeled rigorously. The formulation is such that the p.u.l. impedance matrix for the multiconductor interconnect is extracted directly at a prescribed frequency. Once the matrix has been calculated over the bandwidth of interest, rational function representations of its elements are generated through a robust matrix curve-fitting process. Such a formulation enables subsequent transient analysis of interconnects through a variety of approaches. Direct incorporation of the rational function model into a general-purpose circuit simulator and a standalone multiconductor-transmission-line simulator is demonstrated.
Time Domain Simulation of Lossy Interconnect Based on a Pade Approximation in Frequency Domain
In this paper a frequency domain model of lossy cou-pled t r ansmission lines for time domain simulations is presented. The approach is based on the model of de-layed current components. Signiicant quantities of this model are the current transfer matrix and the character-istic admittance matrix, which are i n g e n e r al frequency dependent, even if the primary transmission line param-eters do not depend on the frequency. These quantities are r equired in time domain. As their frequency depen-dence is not given explicitely, analytical methods cannot be applied for the required t r ansfomation from frequency to time domain. Using the Pad e a p p r oximation the el-ements of these matrices are r epresented by appropriate fractions of polynomials, which can be t r ansformed e asily into time domain after their expansion into partial frac-tions. The approach is examinated with real life transmis-sion line conngurations. Numerical results are c ompared with those of other existing meth...
Modeling frequency-dependent conductor losses and dispersion in serial data channel interconnects
2007
Models of transmission lines and transitions accurate over 5-6 frequency decades are required to simulate interconnects for multi-gigabit serial data channels. Extremely broadband modeling of conductor properties for such high-speed channels is a particularly challenging task for electromagnetic tools. This paper discusses the conductor effects in general and the approximations used in different simulation technologies and tools.
Time-domain modeling of high-speed interconnects by modified method of characteristics
IEEE Transactions on Microwave Theory and Techniques, 2000
In this paper, a new model of lossy transmission lines is presented for the time-domain simulation of high-speed interconnects. This model is based on the modified method of characteristics (MMC). The characteristic functions are first approximated by applying lower order Taylor series in the frequency domain, and then a set of simple recursive formulas are obtained in the time domain. The formulas, which involve tracking performance between two ends of a transmission line, are similar to those derived by the method of characteristics for lossless and undistorted lossy transmission lines. The algorithm, based on the proposed MMC model, can efficiently evaluate transient responses of high-speed interconnects. It only uses the quantities at two ends of the lines, requiring less computation time and less memory space than required by other methods. Examples indicate that the new method is having high accuracy and is very efficient for the time-domain simulation of interconnects in high-speed integrated circuits.
Frequency-dependent losses on high-performance interconnections
IEEE Transactions on Electromagnetic Compatibility, 2001
This paper compares the major classes of chip-tochip and on-chips interconnections used in high-performance computers and communication systems and reviews their electrical characteristics. Measurement results of dielectric loss are shown and the attenuation is compared for printed-circuit-board, glass-ceramic, thin-film, and on-chip wiring. Simulation results are shown with representative driver and receiver circuits, guidelines are given for when losses are significant, and predictions are made for the sustainable bandwidths on useful wiring lengths.

This paper presents a new scheme for generating numerical meshes for computing the frequency-dependent resistance and inductance of transmission lines with rectangular cross-sections. The proposed mesh conforms to frequency-dependent spatial distribution of current. The method ensures accurate numerical solutions with relatively small numbers of mesh elements. The numerical results and the efficiency of our method are compared with those of FastHenry
Electrical Modelling of Multilevel On-Chip Interconnections for High-Speed Integrated Circuits
Active and Passive Electronic Components, 1992
A method for the electrical parameters analysis and modelling of lossy-coupled multilayer on-chip interconnection lines at high bit rates is presented in detail. It can be used by the VLSI designer to analyze on-chip interconnections with linear, as well as nonlinear/time varying terminators and to simulate the pulse propagation characteristics in high-speed integrated circuits. First the capacitance, inductance, conductance and resistance matrices per unit length for the given multiconductor geometry is computed. A multiple coupled line model consisting of uncoupled lossy transmission lines and linear dependent current and voltage sources if finally calculated according to the capacitance, inductance, conductance and resistance matrix values computed.
Crosstalk and transient analyses of high-speed interconnects and packages
IEEE Journal of Solid-State Circuits, 1991
This paper presents a new method for the crosstalk and transient analyses of lossy interconnects with arbitrary termination circuits. In order to analyze an interconnect containing N signal conductors, we first derive closed-form formulas to determine its transfer functions, and then apply the inverse Fourier transform to obtain its time-domain pulse response functions. Two types of equivalent circuit models can be formulated once the pulse response functions of the interconnect are found. The circuit schematics of the models depend on the number of the signal conductors, irrespective of the physical parameters of the interconnect. These models are compatible with standard circuit simulation tools since they consist of linear resistive networks and linear-dependent sources only. Two example circuits are studied to examine the accuracy and efficiency of the present method.
