Defining a Cable Instance

A cable instance is a single cable (for example, ribbon, cable bundle, coaxial cable) with its cable connectors that is routed along a cable path.

  1. On the Cables tab, in the Create instance group, click the  Cable instance icon.

Figure 1. The Create cable instance dialog.
Specify the cable type.

  1. From the Cable type drop-down list, select one of the following options:
    • To specify a predefined cable, select the cable you want to use.
    • To specify a cable, which is not yet defined in the model, click the icon to define a cable path.
  2. Specify the start connector and end connector for the cable.
    1. Under Terminal connectors, from the Source drop-down list, select the start connector for the cable.
    2. Under Terminal connectors, from the Destination drop-down list, select the end connector the cable.

    • To use the cable path with the shortest route between the specified start connector and end connector, select the Select shortest route check box.

For each conductor (signal) in the cable instance, specify the pins of the cable connector to which the conductor is connected.

  • Each conductor in the cable instance is a signal.
  • A signal is connected to the pins of a cable connector.

  1. Under Signals and connections, select the Signal name, Source (start pin) and Destination (end pin) of the connector (specified in Step 3) to which the signal is connected.
