To specify a clock and data frequency, select the Clock/Data frequency cell and type in a new value.
SmartPower defaults to 10 MHz for each clock frequency, and 1 MHz for the data frequency. Input your target for each clock and data frequency (5% of your clock frequency is a typical guideline for your data frequency - this corresponds to a toggle rate of 10%.)
Not all the pins/gates/nets of your design are associated with a specific clock. For example, the frequency of a design input port is not always correlated to a clock frequency. By extension, all pins that are upstream of the first level of sequential elements are not associated with any clock. SmartPower creates an InputSet by default that it uses to group all the pins that are controlled by design inputs (instead of sequential elements). You may wish to view and verify the InputSet to further evaluate your design.
