Connector Refinement and Signal Mapping

Creating Variant Signal Mappings on the Signal Mappings Tab for a

	Slot

You can create variant signals mappings on the Signal Mappings tab of a Signal Map dialog box for a slot. A variant signal is a signal that can travel to different cavities depending on the active options in a vehicle.

Note

A variant wire is a wire that is connected to different cavities depending on the active options in a vehicle. When editing a signal map, variant wires may be created as a side-effect of modifying mappings that already have wiring by:

Refining a connector using the Copy connector action
Creating a copy of a mapping (using the Duplicate Cavity or Copy To action for a mapping)
Defining multiple variance conditions for a signal using the Manage Variance action

Prerequisites

The option codes required for the variant option expressions must exist in the project.

Procedure

Select a slot, a slot’s slot connector or a hole on a slot in the Diagram Window or Design Browser (Design tab) and either:

Right-click the selected object and choose Signal Map.

Press Space Bar and enter Signal Map.

The Signal Map Dialog Box for Slot displays.
Still on the Signal Mappings tab, select the rows for the Signals for which you want to create variant mappings and click the Manage Variance () button; the Manage Variance

Dialog Box displays.

Add the variant option expressions that are applied to mappings for the signals:

Click the Add a new option () button; the Set Variant

Dialog Box displays.

					Define a variant option expression and click OK; the variant option expression
						displays in the Manage Variance dialog box.
				

				
					Repeat steps a and b for each variant option expression
						that are applied to the variant signal mappings.
				

				
					Click OK on the
						Manage Variance dialog box; for each of the selected signal rows,
						duplicate rows are created so that there is one row for each of the
						variant option expressions that you have applied. The Signal and Wire
						columns display the variant option expression in brackets (). In
						addition, a new row is added on the Wire
							Info tab for each mapping of any variant wires.

On the Signal Mappings tab, specify the cavity to which each mapping of the variant signals is mapped.
Note You can move, swap, and copy signal mappings when editing them in the Signal Mappings tab of a Signal Map dialog box. See Moving, Swapping, and Copying Signal Mappings.
