Pin Grouping Request


I’ll inspect the current eMMC symbol, group pins by function (power, ground, data, control, and reserved/NC), then verify the symbol organization.
Grouped all 153 pins by function in the parametric symbol:
  • Power: VCC, VCCQ, VDDI
  • Ground: VSS and VSSQ
  • Data Bus: DAT0–DAT7
  • Command & Clock: CMD, CLK
  • Strobe & Reset: DS, RST_N
  • Reserved / No Connect: NC, RFU, VSF
Pin orientation and ordering were also standardized. All original ball numbers, names, mappings, and assets were preserved.
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.
I’ll assign the ten functional groups orders 1–10, with Power first and Ground last, then alternate the remaining groups between left and right for a balanced symbol.
Updated and verified all 153 terminals:
  • Power groups: orders 1–3, orientation Top
  • Interface/reserved groups: orders 4–9, alternating Left/Right
  • Ground: order 10, orientation Bottom
All pin names, ball numbers, mappings, and group labels were preserved.
