GOF AI · Agentic Netlist ECO Platform

Describe your ECO in English.
GOF implements it.

The first netlist ECO platform built for the AI era. Natural-language ECO, AI-driven non-equivalence debug, and spec-to-RTL generation — on top of 15+ years of production-proven ECO technology.

GOF V11.9 · released Jul 26 2026 · what's new

// your ECO spec, in plain English
Use GOF to do RTL guided ECO on netlist imp_net.v
The library is art.m.simple2.LIB
The original rtl is imp_rtl.sv
The new rtl is ref_rtl.sv
The top level module name is testtop
Set test_mode to constant zero
▸ GOF generates & applies the ECO & runs LEC

Works inside your AI coding agent

GOF runs inside Claude Code, Codex, opencode & more

GOF ships a SKILL.md skill file that teaches your agentic AI CLI how to drive netlist ECO, LEC, and debug directly. Issue one natural-language instruction and the agent generates a GOF run script, executes it, and orchestrates the full GOF workflow — no scripting expertise required.

Switching from Conformal ECO?

Smaller patches, LEC that passes where Conformal's fails, DCT/DCG & DFT cases Conformal errors out on — plus RTL-guided ECO without re-synthesis and an AI agentic platform Conformal doesn't have.

Stop re-running full ECO on every netlist stage.

Run the automatic ECO once on the pre-layout netlist; replay the generated script on the DFT and post-layout netlists in minutes. A full auto-ECO + LEC pass on the shipped benchmark runs in ~12 seconds — the same patch that used to consume hours per stage now ships in a single, fast pass.
