Power Monitoring tool - Arria 10 GX board

I am trying to measure power using the Power monitoring tool. I obtain a static power of 14W. When my FPGA is being programmed I see a drop in power consumption (9W). When I run the application, i do...

    Hi,

    If the graph is referring to Power it doesn’t make sense. I expect Power to spike during configuration, and drops back down in user mode.

    If it is referring to Voltage, it makes total sense. I expect voltage to take a dip during configuration, (depends on regulator feedback response) it will correct it back to the stable 0.9VCC.

    I would suggest a sanity check.

    1) Scope on the VCC line and see if waveform match the powermonitoring waveform during configuration.

    2) Run an EMIF design. It should consume lots of power. I don’t think running a counter + LED will show any significant change in power. Then monitor your waveform and see if match with the powermonitoring.

    Let me know if this has helped resolve the issue you are facing or if you need any further assistance.

    Best Regards,
