Routing through Existing Pathways

This section describes how to route a logical connection or other routable object through existing pathways and route components.

Notes:
  • If you route an object which is part of a group (for example a net group or a cable), all other objects in the group and the group itself will be routed.
  • If you route a group which is itself part of a higher level group, all other objects in the group and the higher level group itself will be routed.

This task shows you how to:

Before you begin: Create or open a logical description of your system with logical components, logical connections, shapes and pathways.

Route Through a Pathway

This section describes how to route a logical connection or other routable object (logical net, net group, logical wire, cable, etc.) through a pathway.

  1. In the 2D graph, select the logical connection or logical object you want to route.
    In the 2D graph, a context toolbar appears.

    In the 3D view:

    • The shapes at the end of the logical connection are highlighted.
    • A line representing the logical connection between the shapes appears.



  2. In the context toolbar, click Manual Route and then select the pathway or pathway segments through which you want to route the connection.
    In the 3D view:
    • The segments are highlighted.
    • The Route Attributes dialog box is displayed and shows the computed length of the route in the pathway segments you have selected.
  3. Optional: Enter values for Segregation and User Length .
  4. Click anywhere in the work area when done.
    The pathway segments are associated with the logical connection and the logical connection is considered to be routed.

Route Through a Logical Shape

This section describes how to define a logical shape as a component through which logical connections and other routable components can be routed.

You will use the Manual Route command combined with the LSR_ValidateRouteComponent business rule.

  1. Ensure that the LSR_ValidateRouteComponent business rule is correctly configured and placed in the appropriate directory (see Related Topics).
  2. To define a logical shape as a route component:
    1. In the tree, right-click the logical shape you want to use as a route component and select Properties.
    2. In the Properties dialog box, under the Representation Reference tab, enter RouteComponent in the Description box.
    3. When finished, click OK.
      The dialog box closes.
    You can now combine the logical shape with pathways to route logical connections and other routable components.
  3. In the 2D graph, select a logical connection.
    In the 2D graph, a context toolbar appears.
  4. Click Manual Route and in the 3D view, select the pathway segments and the logical shape (in this example the logical shape is the sphere).

    Although the logical shape is not a pathway segment, you can select it and use it as such because of the steps you have taken earlier:

    • You defined the logical shape as a route component.
    • You configured the LSR_ValidateRouteComponent business rule correctly and placed it in the appropriate directory.



  5. Click anywhere in the work area to validate.
  6. In 2D graph, select the logical connection to see the cross-highlight in the 3D view.

    In the image above, you can see that the logical 3D Representation is highlighted as part of the route (and is therefore a route component).
  7. Optional: Once the component is selected, set the routed length using the LSR GetLengthOfRouteComponent business rule.

    Note: The LSR GetLengthOfRouteComponent business rule allows you to define the routed length of a component which has previously been assigned as a route component using the LSR_ValidateRouteComponent business rule.
    Important: The routed length value is added to the RoutedLength attribute of the routing connection. If you do not give a route length, it is not considered as an error while computing the route length.
