Abstract

A method can include allowing a user to place a first wiring harness design component within a wiring harness topology in a wiring harness design workspace, allowing the user to place a first plurality of ground devices within the first wiring harness design component placed in the wiring harness topology, allowing the user to request an automatic ground combination, and, in response to the user requesting an automatic ground combination, automatically applying at least one electronically stored ground combination rule to a first set of ground devices comprising a plurality of the first plurality of ground devices and automatically combining at least two of the first set of ground devices into a first combined ground device based at least in part on the applied at least one electronically stored ground combination rule.

Claims

1. A method of combining ground devices in an electronic wire harness design tool, comprising:

displaying a plurality of passive ground devices on the wire harness design tool;

automatically combining by connecting at least two of the plurality of ground devices into a combined ground device according to at least one electronically stored ground combination rule, wherein the ground combination rule is to combine the passive ground devices having a substantially equivalent property, which includes at least one of the following;

having a same color or made from a same material.

2. The method of claim 1, wherein the at least one ground combination rule comprises a user-defined rule.

3. The method of claim 1, further comprising a ground combination rule tool associated with the electronic wire harness design tool and operable to allow a user to create the at least one ground combination rule.

4. The method of claim 3, wherein the ground combination rule tool is operable to allow the user to edit at least one ground combination rule.

5. The method of claim 1, wherein the ground combination rule includes attributes of the ground devices and attributes of ground lines that terminate at the ground devices.

6. The method of claim 1, further including placing a first wiring harness design component in the electronic wiring harness design tool and placing the plurality of ground devices into the first wiring harness design component.

7. The method of claim 1, further including providing a graphical user interface in the electronic wire harness design tool in which the user can select an automatic ground combination function to initiate the automatic combining.

8. The method of claim 1, wherein the at least one ground combination rule comprises a rule setting a maximum number of the plurality of ground devices to be combined into a combination ground device.

9. The method of claim 1, further comprising performing a synthesis operation after the at least two of the first set of ground devices have been combined into a first combined ground device.

10. The method of claim 1, wherein the ground devices that are combined have an equivalent property selected from a group including:

color and material.

11. The method of claim 10, wherein more than one property of the ground devices needs to be equivalent in order to combine the ground devices.

12. One or more computer readable storage devices comprising computer executable instructions for performing a method, comprising:

providing a plurality of passive ground devices on the wire harness design tool;

automatically combining through connecting at least two of the plurality of ground devices into a combined ground device according to at least one electronically stored ground combination rule;

providing a ground combination rule tool associated with the wire harness design tools;

receiving user input to create the at least one ground combination rule using the ground combination rule tool; and

receiving user input to edit the at least one ground combination rule using the ground combination rule tool.

13. The method of claim 12, wherein the ground devices that are combined have a substantially equivalent property, which includes at least one of the following:

having a same color or made from a same material.

14. The method of claim 12, wherein the stored ground combination rule includes attributes of the ground devices and attributes of ground lines that terminate at the ground devices.

15. The method of claim 12, further including placing a first wiring harness design component in the wiring harness design tool and placing the plurality of ground devices into the first wiring harness design component.

16. The method of claim 12, further including providing a graphical user interface in the electronic wire harness design tool and selecting an automatic ground combination function to initiate the automatic combining using the graphical user interface.

17. The method of claim 12, wherein the at least one ground combination rule comprises a rule setting a maximum number of the plurality of ground devices to be combined into a combination ground device.

18. The method of claim 12, further comprising performing a synthesis operation on the wiring harness topology after the at least two of the first set of ground devices have been combined into a first combined ground device.

19. A method of combining ground devices in an electronic wire harness design tool, comprising:

displaying a plurality of passive ground devices on the wire harness design tool;

automatically combining by connecting at least two of the plurality of ground devices into a combined ground device according to at least one electronically stored ground combination rule;

providing a ground combination rule tool associated with the electronic wire harness design tool, which allows a user to create the at least one ground combination rule; and

receiving user input to allow the user to edit at least one ground combination rule using the ground combination rule tool.

20. The method of claim 19, wherein the at least one ground combination rule comprises a user-defined rule.

21. The method of claim 19, wherein the ground combination rule includes attributes of the ground devices and attributes of ground lines that terminate at the ground devices.

22. The method of claim 19, further including placing a first wiring harness design component in the electronic wiring harness design tool and placing the plurality of ground devices into the first wiring harness design component.

23. The method of claim 19, further including providing a graphical user interface in the electronic wire harness design tool in which the user can select an automatic ground combination function to initiate the automatic combining.

24. The method of claim 19, wherein the at least one ground combination rule comprises a rule setting a maximum number of the plurality of ground devices to be combined into a combination ground device.

25. One or more computer readable storage devices comprising computer executable instructions for performing a method, comprising:

providing a plurality of passive ground devices on the wire harness design tool; and

automatically combining through connecting at least two of the plurality of ground devices into a combined ground device according to at least one electronically stored ground combination rule, wherein the at least one ground combination rule comprises a rule setting a maximum number of the plurality of ground devices to be combined into a combination ground device.

26. The method of claim 25, wherein the at least one ground combination rule comprises a user-defined rule.

27. The method of claim 25, wherein the ground combination rule includes attributes of the ground devices and attributes of ground lines that terminate at the ground devices.

28. The method of claim 25, further including placing a first wiring harness design component in the electronic wiring harness design tool and placing the plurality of ground devices into the first wiring harness design component.
