Pin Function Grouping
Worked for 1 min 25 sec
Power, Control, and JTAG are set; I’m applying the same ordering/orientation rules to the Digital I/O and Ground groups now.
Worked for 42 sec
I hit a tool namespace hiccup on the bulk update and corrected course; continuing with the direct schematic edit path so the properties are applied in-place.
Worked for 2 mins 22 sec
Updated and verified all 84 pins.
Mapping applied:
- Power: Terminal Order 1, Top
- Control: Terminal Order 3, Right
- JTAG: Terminal Order 5, Left
- Digital I/O: Terminal Order 7, Right
- Ground: Terminal Order 10, Bottom
Open item:
- Since only Left/Right were allowed for the three non-power/non-ground groups, one side necessarily repeats.
Suggested next step:
- Ask me to visually reorganize the symbol using these section/order/orientation settings.
