Methods of testing time-domain simulators in EDA packages

This paper presents an original approach to estimate the accuracy of numerical algorithms of transient analysis for four test problems. The tests are presented as mathematical models and electronic circuits too. Test problems and methods of estimation of numerical analysis algorithms' accuracy proposed in the present paper can be used in circuit simulators and in computer mathematics programs to test both known and new simulation algorithms for electronic circuits and systems with various dynamics, including stiff and/or oscillating circuits.
