My project is an audio amplifier class D, so it requires high current. for that reason, I have created 2 GND Copper area on both layers i.e, top and bottom. after creating the copper area, I want to connect the 2 copper area using vias, but it is showing error. So, how should I connect the 2 GND Copper areas on my PCB ?
What error is it showing? Your project is private so we can't see and try to replicate the error ourselves.
Is your audio project super top secret or can you actually show it so we can help you?
Are your copper areas nets named the same? GND on top layer and GND on the bottom layer?
Via nets also named GND?
Are the errors about via diameter or hole size? That would be a Design rule error.
Connecting two layers are done with vias, so you have something simple on your hands or a bug.
