Release Date: Jul 26 2026
GOF Platform integrates five functional components, ECO, Formal, LEC, Debug and AI.
Once downloaded, run a real ECO immediately. The bundled examples work in free mode.
The examples/auto_eco folder compares a reference netlist against an implementation and writes the ECO result. Zero dependencies.
tar xzf gof119_centos7.tar.gz cd GOF && make cd examples/auto_eco ../../bin/gof -run eco_example.pl
The ECO'd netlist is written to imp_eco.gv.
The examples/ai_eco folder runs an ECO from a plain-English spec. Install the shipped SKILL.md in your AI CLI (Claude Code, Codex, opencode, Kimi, or Cline), then type the ECO request in natural language. The skill guides the CLI to launch the GOFAI server, create the ECO script, and run it with GOF automatically.
# In your AI CLI (with SKILL.md installed): Use GOF to do eco spec file $GOFDIR/examples/ai_eco/eco_spec1.txt
See the GOF AI workflow and SKILL.md in the release.
