Cyclone V GND pins

In one of our projects, which used 5CGXFC5F6M11I7N (Cyclone V) during the layout had been done mistake. How affected on FPGA if up to 4 GND balls are not connected?

    Hello,

    I am sorry to hear of what happened. Does your FPGA shows any abnormal activities?

    Thanks

      Hello.

      No, the FPGA doesn't show any abnormal behavior.

      Before I give waiver for next PCB assemblies, I just want be sure that won't be any issues with FPGA.

        Hello,

        It seems like your FPGA is working fine. Sometimes FPGA can be damaged over long-term period like example when you set the voltage out of specs.

        Thank you.
