create_soft_fence
-name s_regionName 
{-region {f_xlo f_ylo f_xhi f_yhi} 
| -points {f_x1 f_y1 … f_xn f_yn}} 

Description

Creates a soft fence for an area (rectangle or polygon).

General rules for routing with fences are as follows:

• If all terminals of a net are outside of fence areas, all wiring for the net must be outside of fence areas.
• If all terminals of a net are inside of a fence area, all wiring for the net must be inside of the fence area.
• If terminals of a net are inside and outside of a fence area, then the wiring for the net can cross the fence to make the connection.

The soft fence boundary is viewable in the workspace and its visibility is controlled by the area_boundary:soft fence entry in the Object section of the Layer Object Display Panel.

Arguments

-name s_regionName	Specifies the name for the fence.
-points {f_x1 f_y1…f_xn f_yn}
	Specifies the boundary points for a polygonal fence.
-region {f_xlo f_ylo f_xhi f_yhi}
	Specifies the boundary points for a rectangular fence.

Examples

The following example creates a rectangular fence that covers the current workspace area.
