Detect a machine's environment and install + verify the open-source EDA toolchain that the signoff-loop and def-graph skills need — OpenROAD-flow-scripts (openroad/yosys), iverilog, KLayout, Magic, Netgen, OpenSTA, the sky130A PDK, and the torch+torch_geometric graph venv. Use when setting up a new machine, when `check_env.sh` reports missing tools, when the user asks to install/bootstrap/provision the EDA tools or "set up the environment", or when a flow fails because a tool or PDK is absent.…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# eda-install Skill **Provision the open-source EDA toolchain, then get out of the way.** This is the setup companion to the two working skills: `signoff-loop` (RTL→GDS + signoff) and `def-graph` (graph datasets). It answers one question — *"are the tools this machine needs present, and if not, how do I get them without breaking anything?"* — and acts on the answer. ## The one command ```bash bash r2g-skills/eda-install/bootstrap.sh --dry-run # detect + plan, install NOTHING bash r2g-skills/eda-install/bootstrap.sh # install missing tiers + pin env.local.sh + verify ``` `bash r2g-skills/bootstrap.sh` is a shim to the same script. ## What it does — detect → plan → install → pin → verify 1. **Detect** (`scripts/setup/detect_env.sh`) — a clean `KEY=VALUE` snapshot of the machine: OS + package manager, `HAVE_SUDO`, `HAVE_CONDA`, a big writable volume (≥15 GB, preferring `/proj`), plus every tool + PDK the shared `scripts/flow/_env.sh` resolver already discovers, and a torch-capable python. Absence is data, never an error. 2. **Plan** — `bootstrap.sh` prints a per-tier table (core / frontend / sky130 / klayout / pdk / …

How to install
mdr add shenshan123/r2g-skills/eda-install@sha256:da3bec8d2f14e31bThe line at the top of this page pins the label git:20261023.62ecfc8, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
