I have a question about a schematic of evaluation board provided by a company.
The lower right corner of the schematic below shows a simple circuit for the power supply section of the evaluation board. It seems that there are two ground, one is GND and the other is FG, there can be connected together through a jumper. The components on the board are connected to GND rather than FG.
This kind of design made me confused.
I think in this case, most area of board(copper pour) will be FG, GND only exists in several traces, am I correct? If I am correct, then what's the benefit of doing this?
