1、EVM原理图中0欧电阻R10、R19的作用?是否可不要。
2、关于EVM中个PGND处理,能否向我PCB中的处理方式:就近打孔到DGND层。实现PGND和DGND的连接。

Hi
We originally used 100 ohm series resistors as part of a filter, but these introduced error in current reporting. You can replace the 0 ohm resistors with traces.
为防止检测的noise,建议你放着R10和R19,根据实际PCB的抗噪能力来决定要不要。
