Over heating of ARRIA V

We have a problem of Arria V overheating.

We calculated the heat with the " power play early power estimator".

The results were: Junction Temp, T[SUB]J[/SUB] ([SUP]o[/SUP]C) = 80c

q[SUB]JA[/SUB] Junction-Ambient = 9.1c

Maximum Allowed T[SUB]A[/SUB]([SUP]o[/SUP]C) = 63.6c

Total thermal power = 2.15w.

Our ambient temp is 20c.

We use only 1% of the device logic and 80% memory.

We measured the temperature of the Arria V Package and we got 80c (very hot).

Can somebody assist with this problem?

    Hi,

    Time for a heatsink and fan I think. You can play around with different cooling solutions in power play until you get the predicted temperature down to something more reasonable.

    Mark.
