Folks,
I have a two layer PCB that has, for historic reasons, two different ground planes. These two ground planes are on the bottom of the PCB.
It is important for EMC reasons when having tracks cross the two planes on the top side of the PCB, that underneath those tracks on the top, the two planes on the bottom are joined. I can't find a way of doing this. When I try and draw a third small plane to overlap the edges of the two it, of course, just clears the requisite space according to design rules.
On a previous CAD system I've just been able to "draw" a patch of copper to do this without it being an part of the electrical tests.
Is there a way to do this on Proteus please?
Many thanks.
