15.3.8 Creating a Logical Cone

Use logical cones to view, highlight, and cross-probe a selected subset of your netlist.

You can create as many logical cones as you want. A logical cone displays only the objects you add to it. Initially, the cone does not contain objects.

To create a logical cone:

  1. In NetlistViewer, from the LogicalCone menu, choose Create New Cone.

    A new window appears in which you can add logic to the cone. The name of the new cone appears in the Logical Cones tab of the Hierarchy window.

  2. In NetlistViewer, select one or more objects.
  3. Right-click the selected object(s).
  4. From the right-click menu, choose LogicalCone > Add To Active Cone > Selection.

A Logical Cone window containing only the selected object(s) appears as shown in the following example. You can add and delete objects from a logical cone window.

Note: If no cones exist in the current design, you can skip a step. Just select one or more objects, right-click, and then choose LogicalCone > Add To Active Cone > Selection from the right-click menu.
