Purpose

This category provides a report on cumulative lengths of parallel spacing in a layer. The results can be used for forecasting yields and for planning

Function

Reports parallel lines belonging to different layer nets that are closer than the action parameter pp_spacing . Also measures the overlap of lines (line to line) that are greater than the ERF variable min_line_len (see figure below).

Measurements are lines representing the parallel spacing and overlap. Measurements are reported when both of the following conditions are met:

*         Lines are closer than pp_spacing

*         Overlap between lines is greater than min_line_len

Activation

When spacing_length_measure ERF variable set to Yes .
