20.3.1 Steps to Calculate Power

Use the steps below to calculate the power consumption of your design. The list of screens and steps appear in the order in which you should view them to analyze your power accurately.

1. Summary tab – View global power at the design level and view its impact on junction temperature.
2. Domains tab – Define clock domains and specify a clock frequency and a data frequency for each clock domain.
   1. Analysis tab – View detailed hierarchical analysis of your power consumption. This step is optional. But if your power consumption exceeds your budget, this step will help you to understand where there is room for improvement.
   2. Frequencies tab – Specify individual pin frequencies, this step is optional, but gives you pin-by-pin control of the frequency.
   3. Probabilities tab – Specify probabilities, this step is optional. You can use the default probabilities or set your own.
