I'm still on my first PCB under P99SE. I need to add quite a few extra routes,
but the PCB is really dense. Can I route these on the InternalPlane layers?
Should I have used Polygon pours on ordinary layers instead? If I am allowed to
use the plane layers, then how can I tell whether I'm
Hi Kiernan
You will not be able to route on the internal plane layers.
Any primitives added will simply be voids in the copper
Generally used only if you want to avoid parasitic capacitance on adjacent
layer tracks.
I would use standard route layers and pour ground fill when done.
The polygon
Hi, Kiernan;
Using Mid Layers with Polygon Pours and routed tracks works fairly well.
Obviously, breaks in the Internal Plane can wreak havoc with controlled-
impedance traces, switching-supply circuitry and the like, so it's good
to confine this approach to areas where Plane continuity isn't

There is a way to do this. You can define a new split plane region
for every net you will route on the plane. If there are just a few nets
left to route, and they won't mind a lot of extra capacitance,
