MinWidth Rule

Syntax: MinWidth [Region region_expr] width_in_microns [string]

For the parts of each edge of the source that are not coincident or overlapping with source-compatible figures, a rectangle extending normally from the edge into the source figure by the given dimension is constructed. The test fails if this constructed rectangle is not completely covered by source-compatible figures. Note that the angle formed by two adjacent edges of a figure measured inside of the figure must be 90 degrees or larger, i.e., this rule prevents acute angles in polygons. Figure 10.8 illustrates the test performed under this keyword, for no Region.

The MinWidth test also fails if the length of a line defined by the overlap points of two mutually overlapping corners of a source figure and another compatible figure is less than the given dimension, including the condition where corners of the two figures touch but the intersection area is zero.

Figure 10.8: The MinWidth test. The edge-to-edge spacing across a region on the present layer must not be less than the given dimension.
