{"slug":"shenshan123-r2g-skills","name":"R2g Skills","description":"Claude Code skill for automated RTL-to-GDS flow using open-source EDA tools.","long_description":"# agent-r2g\n\nA Claude Code skill that drives an open-source RTL-to-GDS flow — from natural-language spec (or existing RTL) through synthesis, place-and-route, and full signoff (DRC, LVS, RCX) — using Yosys, OpenROAD-flow-scripts, KLayout, and OpenRCX.\n\nInstall the `r2g-skills` skills (`eda-install` to set up the toolchain, `rtl-acquire` to grow an RTL corpus at scale, `signoff-loop` for RTL→GDS + signoff, `def-graph` for graph datasets), then ask Claude: *\"set up the EDA tools\"* followed by *\"synthesize this UART at 100 MHz on nangate45\"* — it handles everything from provisioning to GDSII. Recent changes: see [CHANGELOG.md](CHANGELOG.md).\n\n---\n\n## Prerequisites\n\n| Tool | Required | Purpose |\n|------|----------|---------|\n| Python 3.10+ | yes | skill scripts |\n| Yosys | yes | synthesis |\n| iverilog / vvp | yes | simulation |\n| OpenROAD + ORFS | yes | place & route, RCX |\n| Verilator | optional | faster lint |\n| KLayout | optional | GDS viewer, DRC, LVS |\n| Magic + Netgen | optional | sky130 DRC / LVS |\n| OpenSTA | optional | standalone STA |\n| sky130A PDK | optional | sky130 signoff |\n| torch + torch_geometric + pandas | optional | PyG graph datasets (`run_graphs.sh`; venv on /proj, `R2G_GRAPH_PYTHON`) |\n\n---\n\n## Install the skill\n\n```bash\ngit clone https://github.com/ShenShan123/agent-r2g.git\ncd agent-r2g\nbash r2g-skills/install.sh --user   # installs eda-install + rtl-acquire + signoff-loop + def-graph into ~/.claude/skills/\n```\n\nRestart Claude Code (or run `/reload`) after install.\n\n**Other options:**\n\n```bash\nbash r2g-skills/install.sh --user            # global — available in every Claude Code session (default)\nbash r2g-skills/install.sh --project .       # local  — scoped to the current project directory\nbash r2g-skills/install.sh --link --user     # symlink — edits are picked up without reinstalling\nbash r2g-skills/install.sh --force --user    # overwrite an existing install\nbash r2g-skills/install.sh --uninstall       # remove all sub-skills\n```\n\n**Installing","tagline":"Agent skill R2G.
