Abstract :
This paper presents a new direct and hierarchical symbolic transient analysis method for linear circuits. Three integration models were implemented symbolically with the trapezoidal method being the most efficient in terms of number of operations. An evaluation algorithm was implemented with a step sizing method based on estimation of truncation error. Test results show the success of the implementation and illustrate the automatic step reduction process necessary to retain numerical evaluation accuracy
