Specifying WSP Options

In the Options page of WSP Manager, you can specify the options to be used when creating, modifying, copying, or generating width spacing patterns.

1. Choose the Spacing Mode from the drop-down list box, Center to Center or Edge to Edge.
   The center-to-center spacing between two tracks equals the edge-to-edge spacing between the tracks plus one-half the width of each track, as shown below:

2. Click the Auto clear name on layer change check box to automatically clear the name in the Layer field on the Edit tab when you change the layer name.
3. Choose the Editing Mode from the drop-down list box, Use WSP Manager (Pattern Viewer read-only) or Use Pattern Viewer (Period and Track table read-only).
   • Use WSP Manager (Pattern Viewer read-only)
     Lets you update the tracks on the Edit tab. Then, you can preview the tracks.
     
   • Use Pattern Viewer (Period and Track table read-only)
     Lets you edit the tracks graphically. The tracks table is updated based on the edits in the preview. You must make the edits in the first period region. The edits you can make include creating shapes, changing the colors of tracks, or deleting, stretching, or moving tracks.
     
4. Click the Enable new def as global check box to make the new WSSPDef as a global WSSPDef and is set globally active if there are no pre-existing globally active definitions on the same layer.
5. Click the Enable def name editing check box to display the WSP Def Name field on the Edit tab that lets you modify the WSSPDef name. The new name is used to create the WSSPDef.
6. Click the Filter Layers to valid routing layers to filter the layers listed in the Layers field on the Edit tab to valid routing layers.
