Adding a
Multicore without an Associated Library Part
You can define a multicore within a harness design, manually enter attributes before adding inner cores, screens, and nested multicores (if required).
Procedure
Press Space Bar and enter Multicores; alternatively, press the shortcut key M, or select the multicore button () from the Home ribbon. The Edit Multicores Dialog Box is displayed.
Click the Add () button.A new multicore is added to the Multicores list, with a default name and a default type of Sheath.
Select the new multicore and click the Edit () button.The Edit Multicore Dialog Box is
displayed.
On the General tab, enter a Name for the multicore or accept the default offered.
(Optional) For each end of the multicore, you can configure cut back attributes (or untwisted attributes for twisted multicores) as well as additional multicore end components on the Ends tab. See also the Edit Multicore dialog box topic.
(Optional) You can configure multicore marker information on the Additional Info tab. See also the Edit Multicore dialog box topic.
The multicore type will default to Sheathed; either leave this selected, or select the Twisted option.
Click OK. The Edit Multicores dialog box displays the new multicore in both the Available and Selected lists.If you are creating a multicore of type Sheathed and have selected the Shielded option, a shield is added to the multicore structure automatically.
To add wires or other multicores (to create a nested multicore), select the item to add in the Available list (with the new multicore highlighted in the Selected list), and then click the Add button.Note Multicores added as a child of another multicore (creating a nested multicore) will be renamed based on the parent multicore name, appended first with innercore and then with an incrementing number, based on the order it was added to the multicore.
Click OK.
Results
- The multicore is added to the Harness Design Browser, along with the wires, screens and any nested multicores configured. Note Once a multicore has been added to a harness design, any wires that were added to the multicore configuration that were not previously terminated at a cavity or splice will still need to be terminated manually.
