Sliver (Sliver) (Signal Layer)

Reports slivers, either between two copper areas (positive layer) or two clearance areas (negative layers), that have width less than pp_sliver, and non-zero.

Purpose	A laminate sliver can cause material to detach during photo-imaging processes in fabrication. Floating pieces can cause defects and shorts which reduce yield.
Function	Reports slivers, either between two copper areas (positive layer) or two clearance areas (negative layers), that have width less than pp_sliver, and non-zero. A sliver is defined by v_dist2sliver_ratio and v_min_sliver_perim. See “Sliver and Short Sliver Categories (Signal Layer Checks)”.
