Purpose

There can be instances where two close features are located in different Layer nets but still belong to the same CAD net (e.g. two ground pads/planes which are connected through other layers). When the system `knows' the CAD nets, it will channel these spacing violations to this category, instead of to the p2p , p2c or c2c categories. This will avoid creating false alarms, since CAD Self Spacing violations are not normally an issue.

Function

Reports non-touching features belonging to the same CAD net that are closer than the action parameter pp_spacing . Measurements are segments representing the distance, if they only touch copper at their end-points.
