Spacing Length (Spacing)

Reports parallel lines closer than pp_spacing belonging to different layer nets.

Purpose	This category provides a report on cumulative lengths of parallel spacing in a layer. The results can be used for forecasting yields and planning.
Function	Reports parallel lines closer than pp_spacing belonging to different layer nets. Also measures the overlap of lines (line to line) greater than 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: Does not report measurements involving features with attribute Copper Feature Ignore.
ERF Parameters	pp_layer pp_spacing
ERF Variables	spacing_length_measure = yes spacing_resolution min_line_len
Constraint	Feature Spacing
Limitations	In rare cases where one of the lines touches another feature in the layer, the action does not report the cumulative lengths of parallel spacing.
