An accurate prediction of the electrothermal behavior of power integrated devices is required to design circuits in an efficient way. An electrothermal simulator (ETS) is a combination of SPICE with finite element code, in a relaxation procedure. It simulates the full electrothermal behavior of integrated circuits. Static and dynamic simulations of typical examples, reveal the value of ETS for high-power applications. Some specific design rules are derived. They are simple formulas, which estimate the temperature (gradients) on chip. They can be used before any CPU-time consuming simulation takes place which allows a more efficient design and prototype phase.
