I'm facing some connectivity error related to subnets of GND even the nets connected. Here is the verify design report and screenshots of subnet #1 and #2
subnet #1 of GND (green) error
subnet #2 of GND error: burgundy is my gnd signal plane, bright green is my power plane, and green is my gnd plane. I don't understand the explanation of the error "COPPER (380,1790 L21). I think its telling me the error is at the xy coordinate of layer 21 but how can I fix it?
Thanks in advanced for your help.
