1.3. Specifying Power Analyzer Input
The Power Analyzer accuracy is driven by design factors, operating conditions, and signal activity data that affect power consumption. The following figure shows how the Power Analyzer interprets these inputs and generates results in the Power Analysis report:
To obtain accurate I/O power estimates, the Power Analyzer requires full compilation of your design, in addition to specifying the following settings:
- The electrical standard on each I/O cell.
- The board trace model on each I/O standard in the design.
- Timing assignments for all the clocks in your design, or use a simulation-based flow to generate activity data.
