Preserving

Wiring during Topology Edits

You can make changes to a design’s topology while preserving any synthesized and edited wiring. Changes to the topology in a design can occur at various stages of a platform’s life-cycle, even after you have determined, or even released, wiring implementation.

In Capital Systems Integrator, wires can only exist if they have a valid path through the topology. Therefore, you must make topology changes in a way that controls and contains any wiring changes in order to preserve as much of the wiring implementation as possible.

To do this, you switch into a Preserve Wiring mode.

Preserve Wiring Mode

In this mode:

  • The system reports in the Output Window when a valid path no longer exists for a wire.

  • If you have wires that no longer have valid path, the only available actions are those that edit the topology (including via Capital Connectors).

  • Saving is not enabled.

  • Wires with no valid paths are not deleted automatically. However, you can commit your topology changes and delete the wires.

  • When a new path is available for a wire whose valid path no longer exists, the wire is re-instated automatically.

As soon as you exit this mode, the system deletes any wires that display in the Output Window because they have no valid path.

Note

A wire can only be re-instated into the same harness from which it was removed. If a harness name is changed during the topology edits (for example, by adding "_split"), preserved wires are not re-instated until you manually rename the harness. Messages in the Design Assistant (in Preserve Wiring Mode) indicate the name of the harness from which each wire was removed. When rejoining harnesses split due to topology modifications, adding a bundle from a stub on the split harness (whether an _split or a newly named harness, for example, H32) to the remaining section of correctly named harness results in a single harness with the original, correct name.

Restriction

Preserve Wiring does not support connector refinement or variant connector scenarios, as it was not designed or implemented for such use cases.
