En IEEE International Symposium on Circuits and Systems (1149-1152), San Diego, USA: Institute of Electrical and Electronics Engineers.0-7803-0593-00271-4310https://hdl.handle.net/11441/94185This paper addresses the topic of formula simplification for symbolic analyzers. Previously reported criteria for flat analysis approaches are briefly reviewed and their limitations illustrated via examples of practical circuits. An adaptive simplification method using pole/zero monitoring for error control is given to alleviate some of these problems. Then a new simplification strategy is presented which takes into account potential ranges of variation of the different symbolic parameters and which overcomes the drawbacks of previous criteria. An algorithm for the approximation of symbolic formula obtained via hierarchical symbolic analysis approaches is also outlined.application/pdf4 p.engAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/conferenceObjectinfo:eu-repo/semantics/openAccesshttps://doi.org/10.1109/ISCAS.1992.23032320392317
