3.3. CTM Top Temperature, TCASE Virtual Sensor

Due to the non-uniform power map of FPGAs, it is not practical to carry out a direct thermal analysis of the part, especially when part of a much larger system model.

For this reason, the CTMs are tuned to accurately calculate a case or top-of-the-die temperature. The TCASE calculated by CFD/CTM can then be compared to the value reported by the PTC. The CTMs have a built-in virtual sensor to report the TCASE value.
