Folks, I just finished the soldering of Arria10 10AX115NF45 chip. After the soldering , I measured the impedance between VCC and GND and found that it was only 2 ohm, between VCCA_PLL and GND was only 20 ohm. Is this normal?At present, the PCB has not been powered on.
Thanks,

Dear Eng Wei
Thanks for your reply, I want to know if the impedance between VCC(0.9V) and GND is too low (2ohm)? Is it damaged or still nomal? I have to make sure the chip is ok before power the board up.
Thanks and best regards,
KUANG Wu

Hi Kuang Wu
We don't have data on this so I am not able to confirm on this. What is the expected measurement? Are you trying to identify whether they are short circuit?
Thanks.

Hello all, I have powered the board on, it is ok, the 2Ω impedance between VCC and GND is nomal.
