Including Electrothermal Effects in Electronics Design with Connected FANTASTIC BCI-ROMs

Modern electronics design demands consideration of electrothermal impacts in many critical design areas. The coupling of thermophysical properties, power dissipation, and temperature is well known, but difficult to consider early in the design process. In order to address these issues, accurate thermal capabilities need to be introduced early in design areas that have traditionally been solely in the realm of electrical engineering. This has not been possible previously as thermal is very much a 3D domain while EDA tools are dominated by 1D and 2D toolsets. To bridge this divide, this work will illustrate how to leverage the FANTASTIC ² reduced order model extraction method to convert 3D thermal simulation models into BCI-ROMs in VHDL-AMS format, and then connect them to form accurate electrothermal circuits in 1D tools.
