Fast novel thermal analysis simulation tool for integrated circuits (FANTASTIC)

This work describes a Fast novel thermal analysis simulation tool for integrated circuits (FANTASTIC), which is fully automated and relies on an enhanced version of the Multi-Point Moment Matching algorithm. The tool provides a novel equivalent network suitable for use in SPICE-like circuit simulators to perform efficient thermal and electrothermal analyses. FANTASTIC requires much less CPU time and memory storage compared to commercial simulators. The thermal behavior of a state-of-the-art four-finger GaAs HBT is investigated as a case-study.
