6.4. CTM Model

The compact thermal model (CTM) for the AGFA01424A Intel® Agilex™ FPGA is shown below, with its mechanical parts listed.

The CTMs for Intel® Agilex™ devices come with the thermal properties built-in for steady state analysis. However, there is no built-in power, therefore you must enter that from the PTC thermal page calculations.
