Stratix® 10 devices are significantly bigger and faster in terms of density and performance than previous generations of FPGA devices. Correspondingly, there is a increase in power consumption even with the increase in power efficiency. Therefore, you should leverage the power reduction capabilities discussed in this application note and ensure that you plan for the thermal implications of the power consumption in your Stratix® 10 FPGA designs. For more information on thermal solutions for the Stratix® 10 device designs, consult your Intel support team.
