Electro-thermal simulation of dynamic circuits in the time domain

It is well known that design and circuit simulation of electric circuits have to thermal effects into account. In this paper, the authors present an approach based on an equivalent thermal network for the determination of the transient electro-thermal solutions. They propose an algorithm for the time domain electro-thermal simulation that solves the convergence and stability problems typical of this analysis. Furthermore, an original estimation of the numerical errors based on the evaluation and balance of energy delivered by devices is shown
