ERF Variable

Description

v_max_oversized_clearance

Value in units, Default = 5 mil

Limit for oversized clearance processing. If optimal clearance is covered with a single clearance from the original solder mask layer, and distance between optimal clearance and original clearance is greater than this variable, the original clearance will be used instead of the optimal. This limitation is designed to eliminate `gigantic' shaves and practically excludes cases of multiple coverage. In complex cases where one original clearance pad covers many pads and shaves, size limitation is applied by testing if the original clearance fits into the limit box of the optimal clearance increased by this variable in every direction.
