Silk Screen Layer treatment |
|
v_keep_away_from_ss
|
If v_keep_away_from_ss
= Yes is
placed into the ERF file, no thieving feature will be placed closer than v_keep_away_ss_dist
distance to any feature in corresponding silk screen layer. If v_keep_away_from_ss
= Yes but v_keep_away_ss_dist
is not set, a zero value is assumed. If v_keep_away_from_ss
is not set to Yes , the
parameter v_keep_away_ss_dist
is ignored. |
v_keep_away_sm_dist
|
|
Solder Mask Layer treatment |
|
v_keep_away_from_sm
|
If v_keep_away_from_sm
= Yes is placed into the ERF file, no thieving feature will be placed closer
than v_keep_away_sm_dist
distance to any feature in corresponding solder mask layer. If v_keep_away_from_sm
= Yes but v_keep_away_sm_dist
is not set, a zero value is assumed. If v_keep_away_from_sm
is not set to Yes , the
parameter v_keep_away_sm_dist
is ignored. |
v_keep_away_sm_dist

Marked features treatment |
|
v_keep_away_from_attr
v_keep_away_attr_dist
v_attr_name
v_attr_val
|
Use these ERF variables when a feature is assigned some
attribute (any attribute except for .pad_usage ) which requires it to be
processed by a specific method (such as, to maintain different spacing
requirements). The following lines represent an example based on the .pad_usage
attribute. Maintain distance from features with a special attribute
set: v_keep_away_from_attr
= yes Maintain this distance: v_keep_away_attr_dist
= 300 Name of the attribute to maintain distance from: v_attr_name
= .pad_usage Value of the attribute to maintain distance from: If v_attr_val
is set to less than zero, it is ignored. v_attr_val
= -1 If v_keep_away_from_attr
= Yes is
placed into the ERF file, no thieving feature will be placed closer than v_keep_away_attr_dist
distance to any feature tagged with the attribute v_attr_name (and v_attr_value set to
desired value, if necessary, or to -1 if the attribute value is to be ignored). If v_keep_away_from_attr
= Yes but v_attr_name
is not defined, the attribute tagged features are ignored. If v_keep_away_from_attr
is not set to Yes,
tagged features are ignored. |
