As the integration density of on-chip transistors increases, high power density exacerbates the reliability of integrated circuits (ICs), limiting their performance. As a result, sophisticated thermalmanagement becomes a key to design reliable and high-performance ICs, which requiring an accurate and efficient thermal simulation framework. However, due to the large computational cost of general-purpose thermal simulators, we need a dedicated one that is optimized for each specific application. In this chapter, first, we will discuss the various thermal simulation algorithms optimized for each target application, particularly at the system and circuit-levels. Second, we present a detailed analytical formula dedicated to circuit-level steady-state thermal simulation. Finally, we compare computational cost of all circuit-level thermal simulation methods in terms of the computational cost.
