The ANSYS SIwave is a dedicated tool that allows users to import electrical CAD (ECAD) data to predict electrical behavior and performance from all major ECAD packages like Cadence, Zuken, and Altium Designer. After the DCIR analysis has been performed in SIwave; IcePak will use the imported power maps for the board to perform a thermal analysis.

In this presentation, we analyzed the thermal behavior of a PCB using SIWave and IcePak. The result shows having a fan is mandatory to cool off the PCB.
