Splices in Capital Wiring Integrator Overview

Capital Wiring Integrator examines the wires connected to the splice and attempts to place each splice in the correct harness. If all the wires are in the same harness, the splice is also placed in that harness.

However, when not all the connected wires are in the same harness, Capital Wiring Integrator attempts to identify the most appropriate harness for the splice using the following rules:

• Splices connecting wires whose paths are mainly on one harness are placed on a bundle on that harness.

• If the connected wires have paths that are equally distributed across multiple harnesses, the splice is placed on the first harness from the alphanumerically sorted list of potential harnesses. It is connected to any appropriate conductors in that harness.

• If none of the connected wires have any paths on the available harnesses, the splice is left unplaced. This means the connected wires are also not routed.

• If the splice is center-stripped, the path of the center‑stripped wires is used to select the harness.

If Capital Wiring Integrator has not identified the correct harness for a splice, you can override the default harness by specifying a Harness attribute for it. When you refresh wiring (or re‑synchronize), the splices will be re‑positioned in the specified harness. See Synchronizing Wiring Changes With a Capital Wiring Integrator Design).

You can then run the Design Assistant to identify routing paths for the unrouted wires connected to these splices. See Using the Routing Assistant to Identify the Possible Routes for One or More Unrouted Wires.

You can also back-annotate the Harness attribute to the splices in the associated Capital Logic Designer designs. See Annotating Topology Wire Lengths and Harness Attributes Back to Logical Design Objects.

When placing a splice within a harness, Capital Wiring Integrator positions the splice according to the wires connected to it. This means, the splice is initially positioned somewhere in the middle of the attached connectors or splices, close to a takeout. The exception to this are shield pigtail splices, which the system places close to the connector where the rest of the multicore is connected.

For example:

Figure 200: Splice in Capital Logic Designer

Figure 201: Splice in Capital Wiring Integrator

In this example, the three wires connected to DEV202 pull the splice across towards the slot.

If you delete two of the wires on DEV202, Capital Wiring Integrator places the splice as follows:

Figure 202: Splice in Capital Wiring Integrator (2)

Now the splice moves closer to DEV200 because of the two wires connected there.

If you used splice separation constraints, they would move the splice away from the takeout. In addition, you can use a constraint to override this behavior and define on which bundle the system places the splice. See Constraining the Placement of Splices on a Bundle for further information about using constraints.
