booley

Booley is an open-source agentic development environment for FPGA and ASIC work: the user directs Claude Code or Codex agents while they do the RTL work. Each Developer Agent runs in a Docker sandbox, is handed real EDA tools, and has its work checked against acceptance criteria the user sets, such as passing tests, area and timing budgets, cycle counts and coverage.

Typed EDA flows replace per-repo glue Tcl scripts: sim, lint, synth and fpga each run an EDA job end to end and return a structured result with pass or fail plus metrics such as area, timing or cycle counts. Simulation and elaboration use Verilator and Icarus Verilog, lint uses Verilator and Verible, synthesis uses Yosys with OpenROAD for physical estimates, and FPGA implementation uses AMD Vivado, with Synopsys VCS and Cadence Xcelium listed as coming soon.

In Goal Mode the user sets mandatory goals up front, such as a synthesis area increase of at most 10 percent or line coverage of at least 90 percent, and Booley checks each one in deterministic code against fresh recorded flow results, not against the agent's claim of success. A bwave command lets the agent query real simulation traces, and sessions, RTL, terminals, EDA runs and waveforms sit side by side in one VS Code window. It runs on Windows and Linux; macOS is not supported.
