Setting a Constraint to Combine Wires at a Cavity

You can set a constraint on a connector, slot or design to trigger the combining of wires at a cavity when the post wiring synthesis action ‘Combine Wires’ runs.

This video shows an example of combining wires using a constraint.

Procedure

1. Right-click a connector or slot (or design in the Design Browser (Design tab) and choose Properties; the Edit Properties Dialog Box displays.

2. Click the Rules tab; the rules and constraints set on the object display.

3. Click the Add Constraint () button; the Constraint Selection dialog box displays.

4. From under the Routing node, choose Combine Wires at Cavity and click OK; the dialog closes and the default constraint appears on the Rules tab.

5. Edit the constraint as required. See the “Combine Wires at Cavity” section in Standard Constraints for Capital Systems Integrator for details of how to edit it.

6. Click OK.

Results

• When synthesizing wiring with the “Combine Wires” action selected, the system identifies cavities matching the constraint. At those cavities, it identifies wires matching the constraint.

• If you did not insert a splice, the wires combine.

• The combined signal and combined wire are created and display in the Design Browser (Design tab).

• If you inserted a splice, the splice appears in the Design Browser (Design tab).

• If another uncombined wire goes to the cavity and you insert a splice for the combined wires, the system connects the uncombined wire to the splice, not directly to the cavity.
