Purpose

A laminate sliver may cause material to be detached during photo-imaging processes in fabrication. The floating piece may cause defects and shorts which reduce yield.

Function

Reports slivers between any two features belonging to the same net. Measurement is included if the sliver width is less than the pp_sliver action parameter but non-zero, and sliver length is greater than the min_sliver_len erf variable.

Measurements are distance segments between the involved features. The distance between the measurement segment endpoints along the net should be greater than the sliver width * dist2sliver_ratio when dist2sliver_ratio is the erf variable.
