what is the Fan Power Header

Hi,

The Fan Power Header (J19) on the Arria 10 FPGA development kit is only intended for powering a fan, it's not designed for measuring or monitoring the board’s power consumption.

To monitor real-time FPGA power usage, your development kit includes onboard current and voltage sensors connected to the MAX V CPLD. You can access these readings using the Power Monitor feature, which is available through the Board Test System (BTS) software or as a standalone application (PowerMonitor.bat). This tool shows real-time current and power graphs for multiple power rails and can display minimum, maximum, and RMS values.

Note:

• Power data is only available through the software interface, there’s no dedicated pin or analog output that you can probe directly with an oscilloscope for total FPGA power.
• Some versions of the software may allow you to export or log power data. Check for any “export” or “log” options in the Power Monitor tool, or consider scripting with Intel’s System Console if you need automated logging.
• If you’re having trouble setting up the Power Monitor, please specify which software version you’re using and describe any error messages or issues.

For more details, see the user guide (Arria® 10 FPGA Development Kit User Guide) sections:

• 4.4.11 The Power Monitor (how to view power data)
• 6.9.2 Power Measurement (hardware details of power monitoring)
