20.2.3.2.3 Breakdown
Displays a breakdown of power usage of the currently selected block. Use the drop-down list to select whether to display the power breakdown by type of component, instance, or clock domain.
When you select By Type from the drop-down list, the Analysis tab displays a breakdown of the selected block's power usage by the following types:
- Net
- Gate
- I/O
- Memory
- Core Static
- Banks Static
- Analog
Any static power used by instances of a component in a design will be included in the appropriate category. As a result, the sum of the power in breakdown by type will equal the total of the static and dynamic power consumption of the design. Percentages displayed are fractions of the total power. Global nets are included in the net power types. To obtain the power of a clock, select breakdown by clock domain.
When you select By Clock Domain from the drop-down list, the Analysis tab displays a breakdown of the power usage by the clock domain that the power is drawn from. For each clock domain, the power and percentage of power drawn are displayed. Dynamic power is accounted for in breakdown by clock, but static power is not associated by any clock.
Whether you selected By Type, By Instance or By Clock Domain, you can customize which columns are displayed in the grid by right-clicking the column headers. To exclude a column, remove its checkmark from the right-click menu. Right-click a column header to set the column default size for the selected column or for all columns, sort the values in ascending or descending order, or customize columns.
