Thermal Junction Temperature Measurement

How was the OMAP junction temperature determined when calculating the junction to board thermal resistance?

I believe this is all calculated through simulation based on the external temperature of the package, table 7-1 of the OMAP3530 datasheet note 2 suggests that the thermal characteristics are based on simulations. In other words, the junction temperature is calculated based on the simulated thermal resistances and the actual external package temperature.

I am somewhat curious why you are interested in this, are you having thermal concerns?
