Sliver (Sliver) (Power and Ground)

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

Purpose	A copper sliver can cause material to detach during photo-imaging processes in fabrication. Floating pieces can cause defects and shorts which reduce yield.
Function	Both ‘Silver’ and ‘Short Sliver’ report slivers, either between two copper areas (positive layer) or two clearance areas (negative layers) (usual case). A violation is reported if silver width is 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 (Power and Ground)”. v_slivers_check_diff_net used in ‘Sliver’ (Signal Layers Checks), is irrelevant here.
