Please confirm that this GND ball is redundant.

[BHunt11]

I need to rework a board, and the rework is easier (less risky) if I can remove a ball that appears to be a redundant GND ball. All other GND balls are connected to GND.

The device is 10AX048H3F34E2SG, pin AN16 (GND).

Thanks,

Hi Bryan,

Sorry but pls on hold your board rework first.

I found a workaround that maybe able to avoid board rework by using FPGA PLL to send clock to clkusr pin directly via some Quartus hacking method.

I will share more detail with you in our forum discussion thread.

Thanks.

HI Bryan,

I am closing this case as well since you have verified the clkusr workaround in the other case.

Thanks.
