6.6. Intel® Stratix® 10 Device with PCIe Thermal Design Example 1

This topic explores the computational fluid dynamic (CFD) analysis of a 1SM21BE Intel® Stratix® 10 device on a two-slot PCIe board. For simplicity, this topic assumes that the FPGA is the only active device on the circuit board.
  1. The first step in the thermal design process is to enter design parameters into the Intel® FPGA Power and Thermal Calculator (PTC) and obtain the thermal parameters. For details on this step, refer to Power and Thermal Calculator (PTC), earlier in this document.
  2. The second step is to obtain the Compact Thermal Model (CTM) for the Intel® Stratix® 10 device. The figure below shows the device layout. We take the device to our CFD model and assign the powers to the dies as shown below.
