The list of system design concerns is growing to encompass additional electrical limitations as the frequency of operation increases. These limitations are being mitigated by increasing bus widths, added material costs, more complex technology, and some changes in physical architecture.

A 3D Global Interconnect Parameter ExtractoR (GIPER) has been developed to provide a practical extraction tool for the full-chip global critical path analysis. It extracts the interconnect parameters (R,C) of a typical global interconnect within several minutes per net on a HP 9000/755 workstation within 5% accuracy compared to full 3D numerical simulations.

This paper describes the transmission line and capacitance measurements made on a 0.25 micron test chip. Transmission lines were characterized to frequencies up to 20 GHz using a Hewlett Packard network analyzer and capacitances were determined using conventional capacitance meter. These measurements will help to develop benchmark capacitance and resistance values of on-chip interconnect structures. Measurements of the physical dimension of the interconnect structures will facilitate the determination of the effects of geometric assumptions made by capacitance extraction tools.

A new approach for the time-domain analysis of transmission lines exposed to arbitrary external fields is presented. The approach is robust enough to make it compatible with virtually any line model and circuit simulator. The deviation between exact values and simulation results is less than 1%.

A new fast method of moments code is used to predict the performance and calculate the electromagnetic properties of packaged, dense, planar microwave circuits. It is demonstrated that circuits as large as transmit/receive (T/R) modules that cannot be simulated accurately with commercial tools can be modeled with this method.

This paper compares a simple quasi-TEM model for coplanar waveguide fabricated on moderately doped silicon substrates to measurement. While the coplanar waveguide currents and magnetic fields are unaffected by the substrate, a simple capacitive model can accurately account for the effects of the substrate.

Summary form only given. The characterisation and design of microwave packaging, and the need for predicting the radiation directivity and interference pattern of novel interconnect structures, and also the necessity for validating simpler models, all require rigorous numerical methods and fast algorithms which allow parallel computing. To this end integral- rather than differential-formulations seem to be advantageous. The various formulations of integral equations in computational electromagnetics involve volume and surface integrals, which, generally, have to be solved numerically. For nearly three decades Harrington's method of moments (MoMs) has been successfully used to discretize these integrals and to obtain reliable approximations to the field solutions. However, MoM has three drawbacks: (1) The resulting (frequency-dependent impedance) matrices are dense. (2) The interaction coefficients (nondiagonal matrix elements) are Fourier-type integrals, and their numerical calculation is comparatively time consuming. (3) The selfaction coefficients (diagonal matrix elements) are Fourier-type singular integrals, and have to be evaluated carefully in Cauchy's sense (Hadamard's finite part). The author's recent efforts to remove these drawbacks have led to the fast-MoM. In many applications fast-MoM eliminates the difficulties in (2) and (3), and if combined with the wavelet analysis relaxes the drawback in (1). In this review the author first briefly points out useful features of the wavelet theory, and emphasizes the role of iterative techniques for solving large matrix equations. He then focuses on the problems in (2) and (3).
