Impact Boundary
The impact boundary is defined as the extension of the bounding box of detected
DRC violations. Specify the extension size to form the impact boundary by
enlarging the bounding box of violations. The default value is 20.0 um.
During the correction, the objects that are totally inside the boundary will be
fixed. Those, which are exactly on or outside the boundary, are immovable.
Correct Order
Specify the sequence of correction direction, either starting correction from
horizontal direction (XStart) or from vertical direction (YStart). By default, the
correction starts from horizontal direction (XStart).
