Hi thanks,

I am sure and checked the VCCB and VCC_PLL pins are not shorted to gnd on my PCB.. also i check impedance of board after full PCB assyembly (Zo) it shows some value NOT SHORT to GND...

Only on second time power up of board (fist time power to VCCB and VCC_PLL) these pins got short to GND (Zo=0)...

I am analyzing the causal..?????

since FPGA IC is costly getting one more IC's takes long time and process.

And

i afraid same issue could reflect on new one too...?????????
