Chip Atlas

The published viewer contains source-identified die micrographs and accepts local GDSII files. Circuit graphs, pad drawings, package photos, slides and traced-layer reconstructions are excluded. The default atlas build enforces an explicit photo review list. Historical research remains private; build_atlas.py --research is for validation only and cannot be published.

A cross-industry reference collection of commercial semiconductors: named chips, model families, source-listed exact orderable parts, source photographs, and annotated maps. It covers computing, accelerators, programmable logic, memory, networking, RF, automotive, embedded control, analog, power, sensing, security, storage, and photonics.

Open the searchable catalog to browse by vendor, domain, visual evidence, or exact part number. The coverage report gives current counts and source boundaries. Coverage is partial; neither a named family nor a source-listed set implies every orderable variant is present.

The original photonics subset retains its 16 annotated die records, 82 image regions, and the linked Infinera map with 489 source entries. Additional maps cover published die labels, source-author circuit identifications, visible physical structures, and manufacturer pad tables. Each region states its evidence and limits. A visible structure can have an unknown circuit role. Records without supporting visual sources remain references. No industry fabrication layouts are included.

Selected TI optical receivers, amplifiers, and a high-temperature microcontroller also have original interactive plots of published bare-die pad coordinates. Point markers are symbolic. Where the manufacturer publishes minimum and maximum pad coordinates, rectangles preserve those bounds. Each plot retains its source datum; an unknown physical origin stays unknown. These views contain no internal circuit geometry.

Open the atlas

Open the hosted interactive atlas. Anyone with the atlas link can view it without signing in. The repository remains private.

This repository is private. Sign in to GitHub with an account invited by the repository owner before cloning it.

git clone https://github.com/bvolkangurses/chip-atlas.git
cd chip-atlas
python3 -m http.server 8000 --bind 127.0.0.1

Open localhost port 8000 and choose Open atlas. The browser application needs no package installation or build step. Its HTML file can also open directly; serving the folder gives more consistent browser behavior.

Images load from their original credited sources; an optional local cache supports the original photonics subset. The original hosted Infinera map is used when its local copy is unavailable. These source views need internet access. GDSII files are read locally in your browser.

Share access

The owner can invite GitHub collaborators to the private repository. Sending its URL alone does not grant access.

The atlas is hosted on GitHub Pages at volkangurses.com/chip-atlas, with no hosting-service branding. Anyone who receives its link can view it. Its pages request no search indexing, but link access is not a privacy barrier. This does not grant access to the private repository.

Explore

Search a chip, model family, or exact part number; filter by domain and evidence type.
Open a Record to inspect its source links, full ordering codes, and separately labeled vendor model numbers.
Select an available source photograph, annotated map, vendor diagram, or published pad-coordinate plot.
Click a region or linked functional block to see its evidence and confidence.
Pan, zoom, switch source images, and filter annotation layers.
Open a GDSII file, select cells, and toggle layer/datatype pairs.
Use the catalog and case template to prepare transceiver comparisons.

No industry mask files are included. Image boxes are approximate regions. Schematics use conceptual placement. Source labels and interpretations do not establish complete chip specifications.

THIRD_PARTY.md	Source terms and credits

The original 2.9 GB research snapshot remains a local archive. Its papers, photos, full article text, copied apps, and datasets are excluded from Git. This repository contains original software, annotations, summaries, and source links.

Optional local image cache

python3 05_Chip_Visualizations/download_viewer_assets.py

This explicitly downloads only the referenced viewer images to the ignored archive folder. It does not add them to Git or grant redistribution rights. Check source terms before reuse.

Build and test

Python dependencies support documentation and collection tools. Node.js runs the GDS parser tests.

python3 -m pip install -r requirements.txt
python3 04_Collection_Tools/build_pad_maps.py --check
python3 05_Chip_Visualizations/tests/check_pad_maps.py
python3 05_Chip_Visualizations/build_atlas.py
python3 05_Chip_Visualizations/tests/check_atlas_data.py
node 05_Chip_Visualizations/tests/test_gds.js
python3 scripts/build_docs.py

The GDS fixture is explicitly synthetic. Tests cover units, layers, hierarchy, transformations, and malformed input. It represents no cataloged industry chip. The viewer accepts uncompressed GDSII up to 64 MiB. OASIS and fabrication signoff are outside its scope.
