Connector Refinement and Signal Mapping

Mapping a Signal Between Cavities on the Halves of an Inline

	Connector

You can use a signal map to map a signal and wire between the cavities of the two halves of an inline pair (either generalized connectors or specialized connectors).

There are several reasons why you may want to do this:

Specific signals are not allowed within a certain proximity of each other.
Positive and negative signals are not allowed next to each other.
A particular cavity may be able to take a thicker wire than other cavities.
You are mapping signals for a particular option to a particular connector.

Procedure

Select either half of the inline pair 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 Inline displays.
On the Cavity Matings tab, each row represents a mating of cavities from each inline half (either Generalized Connectors or Specialized Connectors). Ensure that the cavities of each inline half are mated with each other correctly. Specify any changes in the Cavity columns.
On the Signal Mappings tab, each row represents the signal mapping between mated cavities from the inline halves. For a signal mapping row, select the Signal that is mapped between those mated cavities.
Note If you have not yet synthesized wiring when you edit the signal map, you can select a signal in the Preferred Signal column. This assigns the cavity to a signal and the wiring synthesis process uses this cavity as a preference for the signal rather than using an unassigned cavity or creating a new cavity. See Preferred Signal

Behavior during Wiring Synthesis.

					When there are unmapped signals in the Signal Map dialog box, a message
						displays at the bottom of the Signal
							Mappings tab: There are
							unmapped signals. To view them click here. You can click
						to open a separate Unmapped
							Signals tab that lists the same columns but only the
						rows for unmapped signals. The tab is tearable and can be dragged away
						from its position so that it displays in its own separate window. When
						first dragging the tab to display the separate window, you must release
						the mouse button within the area of the Signal Map dialog box. You can
						then drag the separate window to a location outside of the dialog
						box.

Repeat step 3 for each signal mapping that you want to change.

Click OK.

             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.
