ECOS Studio is an integrated, one-stop silicon design solution that democratizes access to custom silicon. It vertically integrates open-source IP libraries, a robust EDA toolchain, and accessible PDKs into a unified framework, providing an "FPGA-like" experience for ASIC design.
Our goal is to lower the barrier of chip design for researchers, engineers, and students, bridging the gap from RTL design to physical realization.
This repository is organized into four main components:
Desktop application providing an integrated development environment for chip design.
- Visual Workspace Management - Create and manage chip design projects
- Automated RTL-to-GDS Flow - One-click execution from Verilog to layout
- Integrated Tools - Yosys (synthesis), ECC-Tools (placement & routing), KLayout (visualization)
- See ecos/README.md for usage guide
- See ECOS Studio User Guide for detailed documentation
Pre-verified infrastructure for composable design, including configurable SoC templates and common peripherals.
ECOS Chip Compiler (ECC): An open-source chip design automation solution that integrates EDA tools (Yosys, ECC-Tools, KLayout) to achieve complete RTL-to-GDS design flow.
Enabling mainstream manufacturing processes.
Note: This is the initial release of ECOS Studio components. We are starting by providing these foundational open-source tools to the community. More subprojects and advanced features will be added in the future. Please stay tuned for updates!
AppImage is a portable Linux application format — download a single file, make it executable, and run it without installation. ECOS Studio is a GUI application and requires a desktop environment (X11 or Wayland) to run — it cannot be launched from a headless environment. For Linux Desktop x86_64 users, you can download the latest ECOS Studio AppImage from the releases page.
# Download and run ECOS Studio on Linux x86_64
wget https://github.com/openecos-projects/ecos-studio/releases/latest/download/<latest-release-file>.AppImage
chmod +x <latest-release-file>.AppImage
./<latest-release-file>.AppImage# Initialize the repo and required resources first.
make setup
# Prepare ECC. If Nix is available, enter the dev shell before syncing.
cd ecc
nix develop
uv sync --no-build-isolation-package ecc-dreamplace --no-build-isolation-package ecc-tools-bin --verbose
# Install GUI dependencies and start the desktop app.
cd ../ecos/gui
pnpm install
pnpm run devecc is installed in editable mode through the uv workspace. After changing ECC
Python code or the native workspace packages, importing the package again uses
the updated sources and rebuilds editable native extensions when needed.
If Nix is not available, skip nix develop and run the uv sync command in the
normal shell.
Release builds currently require Linux x86_64 with glibc 2.34 or newer:
make buildmake build writes the release artifacts to the repository root build/
directory. By default this includes the Linux AppImage and deb package.
For development, validation, branch, and submodule guidelines, see CONTRIBUTING.md. For GUI and release build details, see ecos/README.md.
