Are you looking to assign signal properties on net?

The property is DIFFERENTIAL_PAIR, This property represents a pair of flat nets that will be routed in a way that the signals passing through them are opposite in sign with respect to the same reference. This ensures that any electromagnetic noise in the circuit is cancelled out.

To specify the DIFFERENTIAL_PAIR property for flat nets:

1. Right-click the design in the project manager and select Edit Object Properties. The Property Editor window appears.
2. Click the Flat Nets tab at the bottom in the Property Editor window.
3. Select the first flat net for which you want to create a differential pair.
4. Select the grid corresponding to the DIFFERENTIAL_PAIR property and specify a name for the differential pair.
5. Select the second flat net for which you want to create a differential pair.
6. Specify the same differential pair name you specified for the first net.
7. Click the Apply button. A differential pair between both the nets is created.

Let me know if you need more information about differential signal symbol.

Yes you got it right, Jeet and thank you for the explanation. It helps. Appreciate the details.

It really did... I have a follow up question as well...

How can I visually confirm that the differential pair is correctly assigned in OrCAD Capture?

To view a differential pair go to Create Differential Pair dialog box, select the Differential Pair option from the drop-down list. All the differential pairs you created in your design appear in Diff Pairs column.

If you want to view differential pairs of a particular type, specify the initial letters of the differential pairs in the Filter text box. All the differential pairs of that particular type will appear in the Diff Pairs column. For example, if you want to view all differential pairs starting with the letter "DP", then enter "DP" in the Filter text box. All the differential pairs starting with letter "DP" will appear in the Diff Pairs column.

Select a differential pair from the Diff Pairs column and click the (>) button or double-click the differential pair. The Selections column will display the name of the nets associated with the selected differential pair. You can use the CTRL or SHIFT keys to move multiple differential pairs to the Selections column and view the nets associated with the selected differential pairs.

Thanks Jeet. You've been helpful.
