3.1.3. Power Tree Design

The Power Tree Design section provides the current and voltage from the report page. The power supply grouping is according to the device pin connection guidelines.

Figure 3. Power Tree Design Section in the Main Worksheet

Select a valid configuration from the Power Rail Configuration dropdown. When the Input Parameters and Power Rail Configuration selections are complete, the power regulator selection will be enabled.

The current values shown for each regulator include the margin for regulator selection purpose. For more information, refer to the Enpirion worksheet.

Errors regarding improper rail grouping may appear in the error window on the Main worksheet when the Power Rail Configuration is selected. The following figure shows an example of the error message in the error window.

Figure 4. Error Window in the Main Worksheet

This occurs when the EPE assigns rails with different voltage requirements to the same group. Since each group is supplied by a single regulator, these errors must be corrected before the EPE can make proper component selections. This is done in the EPE Report worksheet. Refer to the Report worksheet on how to correct the error.
