Auto Creation of Differential Pairs
Differential pairs can be created automatically using net names. Perform the following
steps for auto-creation of differential pairs:
1. In the Net > Routing > Differential Pair of Constraint Manager, select Objects
> Create > Differential Pair.
2. In the Create Differential pair dialog, click Auto Setup.
The
Differential Pair Automatic Setup form opens.
Use this form to create differential pairs based on specific prefixes and filters. For
example, if the net names that form differential pairs are CH1_1553+ and CH1_1553-,
you can set the value of Prefix as CH, + Filter as "+", and – Filter as "-". These settings
will display all nets that begin with CH and end with "+" or "-".
3. Select Create to create differential pairs automatically, and a report is also
created.
