The goal of the Power consumption wizard is to estimate the power consumption of a SoC of the Stellar family. Please note that for the purpose of the example, only the SR6P7G7 model is used.
The power consumption wizard is split into several parts:
- A tree displaying the structure of the power configuration
- The right part will display the details of the tree selected object
The configuration is split between the master blocks and the peripherals blocks. Master blocks contain the clusters, platform, accelerators..., while peripherals contain the various peripheral to be configured.
You can decide to enable or disable the various parts, a disabled part does not participate in the consumption. The enablement/disablement of a part is done whenever you double click on the corresponding node in the tree. You can also use the Enabled toggle button on the right panel. Both possibilities are illustrated below:
NB: Please note that some displayed elements are enabled or disabled according to the current Chip mode.
Depending on the configured parts, the consumption on the various power rails are displayed.
For example in the following picture the user configures the Ethernet peripheral clock to 200 MHz, baud rate set to 1000 bps, on Eth1. The consumption in that case is 15mA.
The multiplication factor helps to adapt the consumption if needed. Consumption provided are worst case figures that you can adapt with the multiplication factor. For example if a only half of CAN instances are used you can apply a 50% factor.
The consumptions are summarized in the tree, but the global consolidation will be visible when selecting the Power consumption node in the tree.
In addition, the configuration details are summarized in a textual area in the "Power consumption" node.
