Value Type

minOuterVertexSpacing constraints have a Value that represents the minimum spacing, in user units.

Examples

The following example sets the minimum spacing to 0.7 user units between the edges of Via1 shapes and any outer vertices of enclosing Metal1 shapes when the Via1 shapes are fully enclosed by Metal1.

Format Example
