Editing the Topology in Preserve Wiring Mode

You can make topology edits in a design in preserve wiring mode. In this mode, the system saves your topology edits while preserving any wiring that it has already synthesized and you have already edited.

Prerequisites

• You must have synthesized wiring. See Synthesizing Wiring.

Procedure

1. Click the Automatically preserve wiring () button on the Status Bar at the bottom of the application so that it looks like ; the system enters Preserve Wiring Mode so preserves any wires with no valid path from now on.

2. Edit the topology as required.If an edit results in a wire no longer having a valid route or an unplaced splice: Capital Systems Integrator switches into Topology Edit mode and only actions applicable for editing topology (not wiring) are available.

The Design Assistant (in Preserve Wiring Mode) displays in the Output Window. It lists any wires that no longer have a valid route and any unplaced splices.

3. Continue editing the topology as required. The list of wires with no valid path and unplaced splices updates in the Topology Edits tab accordingly.Note If there are unplaced splices, you may need to place them manually; a hyper-link displays in the Design Assistant to enable moving or placing the splice. If there are wires with no valid paths and you want to delete them, click the Commit current changes button on the Design Assistant (in Preserve Wiring Mode). When all wires have a valid path, the Design Assistant changes to its normal appearance.

4. If you are making significant changes to the topology, you may want to stop preserving the existing wiring. To stop the system from preserving wiring without a valid path, click the Automatically preserve wiring () button on the Status Bar at the bottom of the application so that it looks like ; the system no longer preserves any wires with no valid paths.Note The system re-instages a wire only into the same harness from which it was removed. If a harness name is changed during the topology edits (for example, by adding "_split"), the system does not re-instate preserved wires until you manually rename the harness. Messages in the Design Assistant 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.

Results

• Wires with a new valid path are re-routed and connected to pins accordingly.

• Wire lengths are recalculated.

• If you have removed a signal through the deletion of an interface connector, the system deletes the wiring for that signal.

• All editing actions are available again.
