FPGA is heated like an iron

Hello! Faced a small problem related to the FPGA family Cyclone IV E EP4CE55 in the BGA-484 case. 1 of 2 FPGAs on the same boards and with the same project is heated like an iron. I power the FPGA wi...

Hi,

Alex has a point. This looks like power short scenario.

  • You can probe and measure the power rail to check for voltage drop as sign of power short issue

Some of the factors are either

  1. On board power rail is shorted
  • You can try check for series inductor or resistor component that you can removed to cut off the power for ease of debug
    • Another typical failure will be on the blow capacitor that sitted between power and ground that caused the short.
    • Basically you need to slowly isolate potential failure parts on your board to find out the root cause
  1. Another possibility is faulty on board power regulator that you need to replaced
  2. FPGA internal power rail is shorted which you need to replaced the FPGA

Thanks.
