Abstract

During the past five years several theoretical advances have been made in the modeling of complex transmission line structures, of the type increasingly employed by the digital electronics industry. However, much work remains to be accomplished, particularly in the conversion of these theoretical developments into computer-aided design (CAD) tools suitable for use by the designers of digital signal and data processors. This paper presents several such design tools which are based upon the quasi-TEM assumption [1]. The integral equation method [2] is selected for the evaluation of electrostatic parameters, including capacitance, inductance, conductance, and resistance matrices, and attenuation factors as well as propagation constants and crosstalks. These parameters are thereafter employed to simulate the waveforms of coupled stripline/microstrip lines by the system decoupling method, which is derived in this paper in a manner simpler than previously described in the literature [3], [4]. The computer codes, along with the graphics input routines, have been integrated into a CAD system, referred to as “MagiCAD,” and are suitable for direct use in CAD procedures for the design of high clock rate digital circuits. Numerical examples, comparisons, and applications are also provided.
