Intel Max 10 FPGA VCC and GND short after few days

Hi, Greetings! History: We are using Intel 10M25SAE144I7G FPGA in the design. Rev1 Board is working fine, in the Rev 2 Board we used the same FPGA design code and some of the pins assigned as input/ ...

Hello,


  1. Are you able to do the IV curve?
  2. how many units observed the same?
  3. can you snapshot the top marking of the fail unit?
  4. Do you want to send the unit for FA?


regards,

Farabi

Hi Farabi,

Thanks for your response!

1. I biased at 1.8V and gradually increased the current till 1A during my debug and observed FPGA heats more than 80 degress, disconnected the power immediately and I haven't done further testing.

2. 4 units at different intervals. Initially it works after continuous usage, it experiences sudden heat and fails!

3. Sure, I'll share by Monday.

4. Currently it is on the board, I need to desolder. I'll update you later on the shipment for FA. Yes, I can send if needed.

5. Any suggestion, what are the possible causes for FPGA failure? I have put design release on hold because of this failure!
