MinSpace Rule

Syntax: MinSpace [Region region_expr] space_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 out of the source figure by the given dimension is constructed. The test fails if the constructed rectangle has nonzero intersection area with source-compatible figures. Note that the angle formed by two adjacent edges of a figure measured outside the figure must be 90 degrees or greater, i.e., this rule prevents acute notches in polygons, and acute bends in wires. Figure 10.9 illustrates the test performed under this keyword, for no Region.

The MinSpace test also fails if the space from a corner of a source figure to another non-touching compatible figure is less than the dimension.

Figure 10.9: The MinSpace test. The edge-to-edge spacing between regions on the present layer must not be less than the given dimension.
