Which parts of the process were used

Transistor voltages and optional devices across the 95 designs

Transistor voltages

3.3 V 1

5 V 95

A design counts for a voltage when its standard cells, SRAM or its own transistors use it. 5 V and 6 V transistors share the thick gate oxide; a marker layer in the layout tells them apart.

Optional devices drawn by designers

Device	Designs	Which
High-resistance poly resistors	1	VCO driven by DAC

Not drawn by any design: Native transistors, 10 V LDMOS, MIM capacitors, MOS capacitors, Unsalicided poly resistors, Salicided poly resistors, Diffusion resistors, N-well resistors, Metal resistors, Diodes, Well diodes, Deep N-well, Bipolar transistors, Schottky diodes, Zener diodes, eFuses, One-time programmable memory, Inductors.

Only devices outside standard cells, SRAM macros and I/O pads count, since every die has those. A single test structure counts the same as a large block.

What fits on 1 mm² of GF180MCU silicon?

Theoretical maximum against what designers achieved

The maximum packs one cell type edge to edge with no room for wiring. Real designs need the wiring. Each box gives the most of a cell that fits with any GF180MCU library, then with the libraries this chip used.

~114k

Inverters per mm²

GF180MCU maximum,
with AS 7t-3.3V inv_2

With this chip's libraries:

7t-5V: 114k inv_1

9t-5V: 89k inv_1

~91k

GF180MCU maximum,
with 7t-5V nand2_1

with AS 7t-3.3V buff_2

With this chip's libraries:

7t-5V: 76k buf_1

9t-5V: 59k buf_1

With this chip's libraries:

7t-5V: 16k dffq_1

9t-5V: 13k dffq_1

34k

Best core average

logic cells/mm² of core — 45% of the buffer maximum

DOTTEE VGA demo (TTGF26a)

42k

Densest 0.1 mm square

logic cells per mm² — 55% of the buffer maximum

BioPulse Tile

23k

Typical project

median logic cells/mm² of core across 39 digital projects (1,000 or more logic cells)

65% of the core covered by logic cells

Percentages compare with the buffer maximum for each design's own library: buffers are among the smallest and most common logic cells, so a design made only of buffers, packed edge to edge with no wiring, would reach 100%.

Swipe the table sideways for more columns.

Core area is the whole project. "Typical" and "best" multiply the core area by this chip's median and best core densities; SRAM and analog blocks take their area out of that. The theoretical maxima fill the core with nothing but that one cell of 7t-5V, the library most used on this chip, edge to edge with no routing.

Pick the tile size your design needs when you submit it to the next Tiny Tapeout chip, by 7 December 2026.

Logic density of every digital design

A digital project here is one with 1,000 or more logic cells. Solid bar: average over the core. Outlined bar: the densest 0.1 mm square outside SRAM, per mm² (a dash where memory covers most of the design). The scale ends at the buffer theoretical maximum (76k cells/mm²). The numbers are core / densest, in logic cells per mm².

Die T26A on wafer.space Run 2

The die as a whole, measured like every other design on its run: its size, pads, process features, density, precheck and photographs. See every design on wafer.space Run 2

Rendered from the layout at 2.5 µm per pixel. Layers: NwellDiffusionPolysiliconMetal 1Metal 2Metal 3Metal 4Metal 5Top metalPad openings

Logic density

Inside the core logic cells per mm²	11k (15% of buffer maximum) over the 12.90 mm² core: what the design itself packed
Inside the seal ring logic cells per mm²	7k over all 19.65 mm² of the slot, pad ring included
Densest mm² logic cells per mm²	23k (30% of buffer maximum)
Core covered by logic	33%
Transistor density transistors per mm²	222k average, 297k in the mm² with the most logic cells

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.

Logic density map

Logic cells per mm² in each square millimetre of the die. Hatched outlines are SRAM macros; the red outline is the densest mm² that avoids them (23k logic cells per mm²), found by sliding a 1 mm square over the die in 0.1 mm steps, so it can straddle the fixed squares and find more than any one of them. Squares at the edges are partial, so they read low.

SRAM macros

The ready-made memory blocks this design uses.

Precheck

Before a design is made, the wafer.space platform checks it against the foundry's design rules. T26A was accepted on this check, and has been checked again since with newer rules.

All 16 steps passed, with 0 KLayout DRC errors, on 2026-07-04.

The steps of the gf180mcu-precheck LibreLane flow, as run by platform.wafer.space. The design was accepted on the newest finished check before it was submitted; later re-runs check the same file with updated rules. KLayout DRC is the sign-off check. Magic DRC is advisory: its count does not stop a design. In the logs, Magic's "Error while reading cell" lines about fill cells are messages from its reader, not check failures.

Data and method

Everything on this page is measured from the public layout; the dates come from the published schedules.

Logic cells are standard cell instances, excluding fillers, taps, antenna diodes and tie cells.
Transistors are places where gate polysilicon crosses diffusion, not counting dummy fill.
Core area is the whole project.
Bond pads are the pad openings in the pad ring, or in a second ring of pads inside it for chip-on-board bonding; probe pads are the others, next to the blocks they test. Letters and logos on the pad layer are not pads.
Theoretical maximum tiles one cell at its placement boundary with no routing.
Densest 0.1 mm square is the best 0.1 mm square anywhere in each die, sliding in 20 µm steps and avoiding SRAM, given per mm².

What is Tiny Tapeout?

Tiny Tapeout is the quickest and cheapest way to get your own design made on a real chip.

Many designs share one Tiny Tapeout chip. Each project gets one or more small tiles, and a multiplexer on the chip connects the one you choose to the pins. Draw your first design in the browser with no experience by following the digital design guide, or write it in Verilog or another HDL; Tiny Tapeout's templates build and check it on GitHub. The chip comes on a demo board that selects your design and drives it.

Tiny Tapeout also runs workshops and supports teaching in universities and schools. Browse every Tiny Tapeout chip and the projects proven in silicon, or read the Tiny Tapeout FAQ.

The Tiny Tapeout demo board, with the socket in the middle where the chip's breakout card plugs in — Tiny Tapeout chips come on a breakout card that plugs into the middle of the demo board. Its RP2350 selects a project and drives its clock; the DIP switches, the seven-segment display and the Pmod headers connect to the project's pins. Render: Tiny Tapeout, tt-demo-pcb, Apache 2.0.

Tiny Tapeout and wafer.space are independent companies that work together (announcement). Tiny Tapeout runs its own shuttles: it takes the projects, builds the die, and sells and supports the chips and boards. wafer.space has the dies manufactured on its GF180MCU runs, and these pages are wafer.space's measurements of them.
