20.3.4 Define Clock Domains and Set of Pins

When you run SmartPower, it researches your existing clock domains and partitions your design automatically. You may wish to review the list of clock domains in the Domains tab to ensure that all the clocks of your design are included in the list. Add or remove clocks as necessary.

To add a new clock domain:

  1. Click the Domains tab, and click the Add Domain button. Select Clock Domain from the drop-down list. This opens the Create Clock Domain dialog box.
