Plane Spacing (Plane Spacing)

Reports features in a positive or negative layer closer than pp_pln_spacing belonging to different plane nets if the measurement segment touches copper only at its endpoints.

Internal ERF Name	<Area>:plane_spacing
Measurement Shape Measurement ID	Segment Any two features
Layers Displayed	Power and ground (or mixed) layer
Graphic
Purpose	When spacing between planes is compromised, shorts can occur between different voltage levels or between power and ground, resulting in non-functional boards.
Function	Reports features in a positive or negative layer closer than pp_pln_spacing belonging to different plane nets if the measurement segment touches copper only at its endpoints. If measurement segment touches copper at any point other than its endpoints, it is not reported.
ERF Parameters	pp_pln_spacing
ERF Variables	max_nfp_net_size
Constraint	Copper Spacing
Limitations	Drawn planes close to each other can produce a large number of measurements. Measurements are not filtered by their proximity to each other.
