DeepDataFlowCHIP DESIGN AI PLATFORM
Introducing G2 · Community Edition

Chip design flows,
all in one place.

A local control center for digital implementation: organize projects, blocks, libraries and design data, launch open-source EDA flows from RTL to signoff, and compare results in a browser on your Linux workstation.

The G2 workspace

From design data
to comparable runs.

G2 brings project organization and flow execution into a browser-based interface. Follow implementation progress, inspect design data and compare outcomes across runs, all from your Linux workstation.

localhost:6003 · Impl Status · gcd
G2 Impl Status view listing three implementation runs of the gcd block, each with a floorplan thumbnail, width, height, runtime, instance count, density, per-scenario timing and flow status.
Three implementation runs of gcd compared in the Impl Status view: floorplan, die size, density, runtime and timing for each scenario, side by side.
01 / ORGANIZE

Projects, blocks & libraries

Keep design projects and their blocks, libraries and data in a consistent, versioned workspace.

02 / RUN

Open-source RTL-to-signoff

Use the bundled toolchain to run complete flows: synthesis, floorplan, place, CTS, route and signoff timing.

03 / COMPARE

See implementation status

Compare runs side by side, including floorplan, die size, density, runtime and timing.

04 / ASSIST

Get started

From download to
a demo project in minutes.

The Community Edition ships with Tcl and Node.js runtimes, open-source EDA tools, three PDKs and ready-to-run demo cases. There is nothing to install system-wide.

Operating system

  • Ubuntu 22.04 / 24.04 / 25.04Full support
  • Rocky / RHEL 8+Platform only

Bundled OpenROAD, Yosys and Verilator need glibc 2.35+.

System packages

G2 uses a few standard command-line tools. On Ubuntu:

sudo apt-get install -y xterm tcsh \ vim-gtk3 firefox tcl coreutils gzip

Build a demo project

One script sets up the gcd and spm blocks used in the tutorials. Also available for sky130 and asap7.
