“…In order to fill this gap, some work has been done over the years in the scientific community, in particular between 90s and 2000s years, by means of Conferences like IEEE-SMACD (Symbolic Methods and Applications for Circuit Design), Special Sessions of IEEE-ISCASs (International Symposium on Circuits And Systems) or IEEE-ECCTDs (European Conference on Circuit Theory and Design), postgraduate dissertations [14], books [15][16][17]. Along these years and in conjunction with these events, several efforts have been done to produce and disseminate software tools for symbolic simulation, both powerful and commercial [18][19] and more simple and free [20,21]. On the other hand, the characteristics of these products were not easily transferable in educational use.…”

The paper presents the main capabilities and the possible applications in the teaching area of Electrical/Electronic Engineering of a software system developed by the authors and aimed at simulating analog linear (or linearized) circuits. The work is the enrichment, enhancement and extension of some programs developed by the same authors along the last two decades and distributed in many schools, institutions, industries, and research centers for different purposes. The feedback (in terms of suggestions, corrections, and improvement requests) has been collected to generate a completely renewed software that could definitely become a really efficient tool in the field of analog circuits, also filling the gap which still exists in the use of very famous and classical circuit simulators (as, for instance, the SPICE family). The application of the past experience involves several courses, as it will be described in the final sections of paper. ß 2015 Wiley Periodicals, Inc.

“…The maximum error between the original network function and its approximation was less than 0.5 dB on measured frequencies. The polynomial coefficients of the approximated transfer function can be obtained, for example, using the SNAP program [12] . , , , In the next step, the unknown parameters L 1 , C 2 , R 1 were estimated by the parametric fault diagnosis.…”

The paper shows a procedure for testing large analog circuits or circuits with parasitic parameters via multi-frequency parametric fault diagnosis. To simplify and accelerate calculations the approximate symbolic analysis is used and unknown tested parameters are analyzed in separate frequency bands. Classification of unknown parameters into frequency bands is based on sensitivities. The proposed procedure is shown on parametric diagnosis of an EMI filter.

The paper presents the theoretical background and implementation details of a multi-domain symbolic analysis program developed with the emphasis on linearized hybrid systems combining classical electrical circuits, controllers, electro-mechanical converters and mechanical parts of electric drives. The systems analyzed can be composed of both basic elements and more complex behavioral blocks (regulators, converters, drives, etc.). All models are defined in an easily extensible library. Implemented algorithms for equation/matrix-based symbolic simplification allow obtaining symbolic expressions of acceptable complexity even for larger systems.
