GOF · Functional netlist ECO platform

Close difficult netlist ECOs
without re-synthesis.

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.

Run your ECO with GOF → See a real benchmark

Free for small netlists · Production evaluation for your design · GOF V11.9, released Jul 26 2026

// a difficult ECO, closed with evidence
RTL change → implementation netlist
DFT / scan constraints preserved
Spare cells mapped for post-layout
Generated patch replayed by stage
✓ Patch produced   ✓ LEC checked   ✓ Script retained

Built for ECOs that block tape-out

One platform for the hard parts of netlist ECO

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.

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.
