To verify the InputSet:
Click the Domains tab and select the domain named InputSet in the list.
Verify the list of pins of this Domain. All the input ports of your design (except the clocks) belong in the InputSet. Also, all the pins that are between these input ports and the first level of sequential elements belong in the InputSet. You can add or remove pins as necessary.
Specify an average input frequency. SmartPower uses the same frequency for all pins of the InputSet. The default InputSet frequency is 1 MHz. Type in a new value to change it.
You may wish to split the InputSet into several sets in order to specify different frequencies. A classic example is to create a ResetSet, a reset tree with a very low frequency.
To split the InputSet into several sets:
Create a new Set of Pins. In the Domains tab, click the New button, and select Set of Pins from the drop-down menu. In the Create Set Of Pins dialog box, type a name and a frequency for the new set and click Create. The new set of pins appears in the Domains window. You can only create an empty set of pins, but it is possible to add pins in this Domain latter.
Remove a group of pins from the InputSet. Click the Domains tab and select the domain named InputSet in the list. Select the pins that you want to remove and click the Remove button.
Add this group of pins in the new set of pins. Click the Domains tab and select the newly created set of pins in the list. Highlight the pins in the list of pins that are not yet in a domain, and click the Add button. Repeat these three steps as necessary to create multiple inputs sets.
