6.1. Device Selection and Analysis Example

This section illustrates the setting of Intel® FPGA Power and Thermal Calculator (PTC) parameters for an example thermal analysis of a PCIe board. The first step in the design process is to select an FPGA device.

For the purpose of this example, choose a AGFA014R24A Intel® Agilex™ device, which has E and P transceiver tiles in addition to the core die.
