ERF Variable |
Description |
v_keep_clr_shape
|
Yes : The algorithm will (try to) detect the shape of
clearances. No : Round clearance shape is assumed for all clearances. |
|
|
v_clr_shape_tol
|
Tolerance used for clearances' shape detection. |
v_max_net_size
|
Copper planes (layer nets) consisting of more than this
number [ v_max_net_size
] of shapes will be ignored. This improves the performance of the algorithm. |
v_allow_joint_clr
|
Yes : Clearances which are joined after the enlargement
will be unified. No : Clearances will be kept separated. |
v_subtract_from_surface
|
Yes : If the copper planes are represented by contourized surfaces
where the clearances are represented by holes, optimization will be carried
out by reshaping the holes. Otherwise (i.e. the copper planes are drawn),
optimization will be carried out by adding negative features to the layer. No : Optimization will be carried out by adding negative
features to the layer [regardless of the plane's structure]. |
|
|
v_ignore_npth
|
Yes : Ignore NPTH drills No : Optimize clearances around NPTH drills also |
