Spacing — Reports spacing violations between pads, circuits and nets, and between text to text. Also reports shorts and spacing between different CAD nets and close distances between non-touching features on the same CAD or Layer nets.
Drill — Reports distance violations between NPTHs, PTHs, Vias, and pads, circuits, annular rings and copper. Also reports missing pads.
Size — Reports sizes of pads, shaved lines, text, line neckdowns, arcs and shaved arcs.
Sliver — Reports on slivers between lines and pads or between pads and pads. Slivers between two features with the Copper Text attribute are ignored. However, a sliver between a text feature and a functional pad are reported. See “Sliver and Short Sliver Categories (Signal Layer Checks)”.
Stubs — Reports unconnected line endpoints.
SMD — Lists SMD pads, reports on pitch of SMD pads, and identifies SMD packages.
Bottleneck — Reports thin copper surfaces which could break during assembly.
Exposure — reports distances between exposed vias to exposed vias, toeprints, or copper on outer layers.
