P. Wambacq et al., SYMBOLIC NETWORK ANALYSIS-METHODS FOR PRACTICAL ANALOG INTEGRATED-CIRCUITS - A SURVEY, IEEE transactions on circuits and systems. 2, Analog and digital signal processing, 45(10), 1998, pp. 1331-1341
A comparative study of symbolic network analysis methods for analog in
tegrated circuits of practical size is presented. The methods are comp
ared with respect to two important criteria: 1) the running time limit
s of the different algorithms used within every method and 2) the numb
er of terms that are generated needlessly, i.e., generated invalid ter
ms and cancelling terms. The methods are compared for several analog i
ntegrated building blocks. The results indicate that conclusions about
the efficiency of the different symbolic analysis methods based upon
comparisons for small circuits, can be misleading. The study also allo
ws the reader to make a good choice for a symbolic analysis method as
the core routine of a modern symbolic analyzer with symbolic simplific
ation capabilities.
