Managing Cavity Allocation

You can connect wires from to cavities under the same harness. The allocation is the process of reconnecting a wire that is at first connected to a logical cut or derivation, to a physical connector.

This task shows you how to:

Before you begin:
  • Open the net and wire definitions.
  • Define a physical object for a terminal block or a disconnect.
  • Reserve Cavities

Creating an Allocation

  1. From the Net to Wire section of the action bar, click Wiring Definition Assistant .
  2. To create a pending allocation:
    1. In the Net or Cable tab, select a wire.
    2. In the Reservation, Cavities, or 3D View tab, select a cavity.

      Note: You can also drag the wire on the cavity.

    3. Click Create Allocation .
    A pending allocation is created on condition that:
    • You have reserved the cavity.
    • The wire is not already allocated.
    • The cavity and the wire belong to the same harness.
    • On an interface container, if the mating cavity is allocated, the cavity must be connected to a wire of the same net.
    • On a derivation container, every cavity of the same shunt must be allocated to wires coming from the same net

    A net can be allocated to the shunt of a terminal block. You can create the pending allocation between a shunt and a net directly. The wire is automatically allocated to the cavities with no specific rule.

    If every element inside an element is allocated, that element is allocated. For example, if every wire of a cable is allocated, that cable is allocated.

  3. To validate the allocation, click Apply Allocation .
  4. To find an allocated element, right-click an allocated wire or cavity, and click Find Allocated.

    Note: You can select the wire or the cavity in the Net, Cable, Reservation, Cavities, or 3D View tab.

Launch an Automatic Allocation

Through the automatic allocation, you can determine an allocation inside an interface container.

Inside an interface container, logical cuts can be connected to each other to fulfill the production break. When one side of the cut is allocated, the other side must mirror the requirements of the first side. Two mating cavities cannot be connected to different nets to avoid the cross between the signals.

  1. From the Net to Wire section of the action bar, click Wiring Definition Assistant .
  2. In the Active Harness list, select a harness, and click Automatic Allocation .

    Note: The cavities whose allocation can be computed have the Automatic allocation available status.

Fix Allocation Errors

You can fix errors related to the net continuity on interface containers. This type of error occurs when two mating cavities are connected to wires coming from different nets.

  1. From the Net to Wire section of the action bar, click Wiring Definition Assistant .
  2. In the Active Harness list, select a harness, and click Automatic Allocation .

    Note: The cavities with an error are identified by the Net discontinuous status.

Delete an Allocation

You can delete a cavity allocation.

  1. From the Net to Wire section of the action bar, click Wiring Definition Assistant .
  2. Select an allocated element:
    • A wire
    • A cable
    • A cavity
    • A net
    • A shunt
    • A harness
    • A connector
  3. Click Delete Allocation .
  4. To validate the deletion, click Apply Allocation .

For cables, deleting the cable allocation also deletes the allocation on its wires.
