The problem is as following:

The grounds of two chips are connected, but one chip's return current is so big that makes big voltage drops at the ground of another chip. The big voltage drops makes the effected chip to shutdown.

Right now I want to split the ground to make them connect with power ground directly.

But the problem is that the effected chip is much more closer to the power ground than another one and I do not have time to change the layout.

I want to attach a power ground connector to the ground of chip producing big current without splitting the ground.

Do you think my idea is fine?

Any suggestions are appreciated.

as i understand ur problem will vanish if the pcb track has zero resistance
u can achieve that by widden it
but if u already made the layout u can put a wire parallel to it
