Using the Variable-Length Arithmetic for an Accurate Poles-Zeros Analysis

Original language description

An original software tool called CIA (Circuit Interactive Analyzer) is frequently used for the poles-zeros analysis, which is not present in the PSpice family. In the paper, a reduction algorithm for transforming the general eigenvalue problem to the standard one is presented for both classical full-matrix methods and a sparse-matrix technique appropriate for large-scale circuits. An optimal pivoting strategy for the two methods is proposed to increase the precision of the computations. The accuracy ofthe algorithms is furthermore increased using longer numerical data. First, a long double precision sparse algorithm is compared with the double precision sparse and full-matrix ones. Finally, the application of a suitable multiple-precision arithmetic library is evaluated.
