Usage Example - Giving Away an Option on a Harness

The following usage example demonstrates how to specify an option as giveaway for a harness and view the difference that this makes to the number of harness levels.

Note

This example was created using an earlier version of Capital. Various dialog boxes may have been updated since the screen shots were created. However, the example still shows the relationships between the different types of composite data.

This example uses an Automotive Generative project and references the Vehicle Topology diagram of the Sports Coupe design in that project.

Edit the Vehicle Models So That Giveaway Options Are Required

Giveaway options are specified to reduce the number of buildable harness levels that are generated by Composite Wiring Synthesis (CWS). However, this Automotive Generative project data has only a small number of harness levels defined due to the highly constrained vehicle models.

Therefore, it is necessary to edit the default vehicle models in this project to use this data for this example.

Procedure

Press Space Bar and enter Models; the Define Vehicle Models dialog box displays. By default, they are defined as follows
Edit the values for the Fog Lamps-REAR and Fog Lamps-FRONT options so that they are optional for the RHD-BS (Right Hand Drive - Basic) model and LHD-BS (Left Hand Drive - Basic) vehicle models. To do this, click the table cells and select OPT from the drop-down list. The table should look as follows:

This indicates that you can build the RHD-BS and LHD-BS vehicle models both with and without the Fog Lamps-REAR and Fog Lamps-FRONT options. This means that Composite Wiring Synthesis (CWS) generates more harness levels than it would have otherwise.

Click OK.

Run CWS to Generate Harness

Levels for the Harness

In a standard flow, you would typically run Modular Wiring Synthesis (MWS) to identify the options affecting each harness. The abstract harness levels (and their wiring) are a side-effect of this (and are often not really needed). Having run MWS, you then generate a material statistics report to view information related to option costing and use the report as a basis to work out which options you want to give away. Having specified the giveaway options, you would then run CWS to generate physical harness levels.

For this example, you skips MWS and immediately runs CWS to generate physical harness levels. This is so that you can view the full set of levels that are generated. Note that, in a full vehicle, you would not normally do this because CWS can generate thousands of levels per harness.

Procedure

Press Space Bar and enter Synthesis; the Wiring Synthesis Dialog Box displays.
Select Full Synthesis. Note As your aim is only to generate physical harness levels, you could select just the Update Harness Options and Generate Physical Harness Levels steps. This would give slightly different results because the system combines some harness levels when you select Full Synthesis steps.

Click Go; a progress bar displays.

When CWS is complete, click Close; the system has synthesized wiring for all signals and has generated physical harness levels for the harnesses.

View the Harness Levels for

the IP Harness

You could view the harness levels for any harness but you concentrate on the IP (Instrument Panel) harness.

Procedure

Right-click the IP harness in the Design Browser (Design tab) and choose Define Harness Levels; the Define Harness Levels - Harness:IP dialog box displays.

It lists the seven harness levels that the system has generated for the IP harness:

In particular, you are interested in the relationship between the harness levels and the Fog Lamps-REAR and Fog Lamps-FRONT options. You can see that some of the harness levels do not support either one or both of those options. Therefore, they could be specified as giveaway on the IP harness in order to reduce the number of harness levels.

Specify the Fog Lamps-REAR and Fog Lamps-FRONT Options as Giveaway for

the IP Harness

This is done from the Define Harness Levels - Harness:IP dialog box.

Procedure

Click the Give away options () button; the Give Away - Harness:IP dialog box displays.
Select the Fog Lamps-REAR and Fog Lamps-FRONT options in the Available window and click Add; the options are added to the Selected window.
Click Recalculate; the Estimated Level Count value changes to an estimation of the number of harness levels that would be generated by CWS for the IP harness with those two options as giveaway.
Click OK; the options are saved as giveaway and the dialog box closes. Nothing changes on the Define Harness Levels - Harness:IP dialog box at this point.
Click OK to exit the Define Harness Levels - Harness:IP dialog box.

Run CWS to Re-generate Harness Levels

CWS re-generates the harness levels and treats the Fog Lamps-REAR and Fog Lamps-FRONT options as giveaway on the IP harness.

Procedure

Press Space Bar and enter Synthesis; the Wiring Synthesis dialog box displays.
Select Generate & Finish and click Go; a progress bar displays.
When CWS is complete, click Close; the system has re-synthesized wiring for all signals and has re-generated physical harness levels for the harnesses.

View the Re-generated

Harness Levels for the IP Harness

Procedure

You could view the harness levels for any harness but you concentrate on the IP (Instrument Panel) harness again.

Right-click the IP harness in the Design Browser (Design tab) and choose Define Harness Levels; the Define Harness Levels - Harness:IP dialog box displays. It now lists three harness levels that the system has generated for the IP harness:

You can see that the Fog Lamps-REAR and Fog Lamps-FRONT options are now present on all three harness levels.
