GOF · Functional netlist ECO platform
GOF closes RTL-guided, DFT-aware, post-layout, and metal-only ECOs with an auditable patch and built-in LEC. Use the AI agentic workflow when it helps; rely on the same production ECO engines throughout.
Free for small netlists · Production evaluation for your design · GOF V11.9, released Jul 26 2026
Built for ECOs that block tape-out
Whether the blocker is a missing reference netlist, DFT constraints, a post-layout spare-cell limit, or an ECO that does not pass LEC, GOF is designed to produce a verifiable result instead of another manual iteration.
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.
See the side-by-side comparison →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.
