Under the Hood - ANSYS Advantage - Article - V10 I1

The electronics in modern automobiles must operate in a high temperature, under-hood environment without sacrificing performance or reliability. The traditional approach to thermal design, which is based on the assumption that the entire integrated circuit (IC) is at a constant temperature, is fast becoming obsolete as higher power dissipation and shrinking form factors make thermal design more critical. NXP engineers use ANSYS tools to calculate temperature and current density throughout the device, making it possible to predict local junction temperatures more accurately and perform thermal-aware electromigration (EM) analysis.
