Stratix5 - VCCCORE to GND resistance is almost 0 ohm

Hi, We have designed a PCB for the Stratix V device. We found the resistance between VCCCORE and GND is almost 0 ohm, thus we never powered it up. To clarify the problem, FPGA was di...

Hi,

1.Are you sure you got 0.02 ohm after probing FPGA vcc core and Gnd?

2.Have you checked the board ?(Converters, regulator & passive components in the path)

It is a short as per your value.
