Abstract

We demonstrate how to apply VHDL-AMS to modelling a coupled distributed electrothermal problem. We present an example of a simple system where two resistors on top of a silicon substrate are thermally coupled. Thermal exchange is described with a heat balance equation discretized and solved using finite difference method. The entire system is modelled in VHDL-AMS. Our work is a tutorial demonstration of VHDL-AMS capability to model coupled electrothermal systems beyond the traditional equivalent thermal network representation.
