Pin Function Grouping

Looking at the datasheet of this component, can you group together pins by their functions? for example for Power, 3v3, gnd_1 gnd_2 etc NOTE: If you group them, can you not add the same pin if you already added them in a group? You should know which pin function is common for its function

I’ve made a plan and started work on it.

Plan

#Goal

Group the TPS25940LRVCR pins based on their functional roles defined in the Texas Instruments datasheet, ensuring each pin is assigned to exactly one group (e.g., Power, Ground, and control groups).

#Implementation plan

Review the TPS25940LRVCR datasheet from https://www.ti.com/lit/ds/symlink/tps25940.pdf to extract the complete pin list and their corresponding functions.
1. Identify and list all pins (like VIN, VOUT, GND, ENABLE, etc.) and their functional designations.
Define functional groups based on the datasheet information:
1. Create at least a Power group (e.g., VIN, VOUT), a Ground group (e.g., GND), and additional groups for control or other functions if applicable.
Update the project terminal properties for TPS25940LRVCR:
1. Assign the Pin Group, Section, Pin Type, Pin Orientation, and sub-symbol/grouping properties for each pin, ensuring no pin appears in more than one group.
2. Make explicit note if certain pins can be grouped together based on their electrical roles.
Verify the total pin count matches the datasheet and that each pin is present in only one group.

#Success criteria

The TPS25940LRVCR has all its pins grouped exactly once according to the functional distinctions in the datasheet.
No pin is inadvertently assigned to multiple groups, and every group appropriately reflects its intended purpose (e.g., Power, Ground, Control, etc.).
Confirmation that the updated terminal list aligns with the pin count and layout specified in the Texas Instruments datasheet.
