115 logic cells: too few for density figures, which are given for designs of 1,000 or more.
Every figure here is measured from the public layout, the same way for every design on the run: see data and method, and how its designs used the process.
Drives a 7-segment display to show the word posoco2000.

Process features
Which parts of the GF180MCU process this design uses: its transistor voltages and where they come from, its gate oxides, and any devices drawn by hand outside the standard cells, SRAM and pads.

|---|---|
| Gate oxides | Thick only (5 V/6 V) in the design itself |
Where the area went
How this design's area splits between filler and tap cells, other and outside the user area.
- Filler and tap cells 0.07 mm² (<1%)
- Other 8.92 mm² (44%)
- Outside the user area 11.12 mm² (55%)
