Cyclone V Thermal Power Dissipation and Heat sink

Hi,

I am using Cyclone V FPGA 5CEBA5F23C7 in my deign. Based on my design compilation I found that total thermal power dissipation is 638mW (with Low power estimator confidence) while my logic utilization is 31% (other compilation summary details attached).

So my question is does 638mW looks a considerable value of thermal power dissipation for such a design. I don't have a Modelsim license to generate .vcd file (to improve power estimator confidence) and the code is more than 10000 lines so I cant use Intel-Modelsim starter edition.

Kindly help!

Thanks

    Try exporting you information to EPE. In Quartus, Project --> Generate Early Power Estimator File.

    Import this file into CV EPE. It is easier to change your parameters from the xls sheet.

    Example: Change the parameters accordingly to best match your cooling solution. Change all your static signals to 0 toggle rate, etc.
