ATWILC3000 Pin Review
-
Make the functional group more general.
-
Add a Section property to all pins, and apply the same value used in the Pin Group property to each pin's Section property.
Assign a Terminal Order from 1 to 10, starting with Power. Power should be Terminal Order 1, and Ground should be last, Terminal Order 10. For Orientation, set Power to "Top" and Ground to "Bottom." For the remaining sections/groups, you may decide the Terminal Order and Orientation yourself. For Orientation, distribute them between "Left" and "Right" — don't put everything on one side. Each group/section should have a different orientation.
Thought for 10 sec
I’ll generalize the pin groups, mirror each group into Section, and rebalance Terminal Order/Orientation with Power at top/order 1 and Ground bottom/order 10.
Worked for 6 mins 36 sec
Updated all pins as requested.
Open items:
- None for this grouping pass.
- Existing pin-description note remains: pin 34/35 labels still appear swapped versus the datasheet, but I did not rename pins because this request was only for grouping/section/order/orientation.
Suggested next steps:
- Rename/swap pin 34 and pin 35 labels to match the datasheet.
- Rename pin 37 to
PADDLEorPADDLE/VSS. - Review the generated symbol visually and adjust left/right balance if you want a different layout.
