“…The analytic forward solver approach supports analytic time-domain transient analysis for switched networks with piecewise-linear models and uses analytic methods for solving the systems of ordinary differential equations (ODEs). Symbolic simulators like ISAAC (Gielen et al, 1989), SAPWIN (Liberatore et al, 1995;Fontana et al, 2015) and Analog Insyde (Thomassian, 2007) exist. These simulators do not support fully analytic timedomain transient analysis for switched networks with piecewise-linear models.…”

Purpose The purpose of this paper is to evaluate the worst-case behavior of a given electronic circuit by varying the values of the components in a meaningful way in order not to exceed pre-defined currents or voltages limits during a transient operation. Design/methodology/approach An analytic formulation is used to identify the time-dependent solution of voltages or currents using proper state equations in closed form. Circuits with linear elements can be described by a system of differential equations, while circuits composing nonlinear elements are described by piecewise-linear models. A sequential quadratic program (SQP) is used to find the worst-case scenario. Findings It is found that the worst-case scenario can be obtained with as few solutions to the forward problem as possible by applying an SQP method. Originality/value The SQP method in combination with the analytic forward solver approach shows that the worst-case limit converges in a few steps even if the worst-case limit is not on the boundary of the parameters.

“…Findings include: the software was handy in enhancing practical tasks at home and some issues related to the fact that professors are not able to follow their student's activity in real‐time. Finally, the benefits of using Analog Insydes as a teaching tool in the electrical engineer program at the SUNY Maritime College, in New York, are discussed in [27], for the Microelectronic Circuits courses I and II. The findings comprise that students considered that Analog Insydes was useful in learning new concepts and handy for a better understanding of the topics revised during the courses.…”

EI-SCAM is a very useful tool capable of carrying out symbolic, semi-symbolic, and numerical solutions for the electrical variables of a circuit under analysis. The goal of the research reported herein is to assess the effectiveness of the program as a teaching tool for circuit analysis of Automotive System Engineering students. To this aim, EI-SCAM has been used for at least 5 years, from 2017 to 2021, in the undergraduate course Interfaces, Communications,
