ONE CONNECTED PLATFORM

Precision at every stage of change.

ECO, verification, and debug tools built around the same gate-level design. Start with the capability your flow needs.

01

GOF ECO

Create functional patches with RTL-guided, script-driven, and spare-cell ECO flows.

Explore GOF ECO
02

GOF AI

Turn natural language requests into GOF scripts and bring AI assistance to ECO and debug.

Explore GOF AI
03

GOF Debug

Trace logic in incremental schematics and investigate non-equivalent points.

Explore GOF Debug

BUILT AROUND YOUR DESIGN

Find the flow for your next ECO.

Use cases
01

RTL-guided ECO

Apply RTL changes to an implementation netlist and replay generated scripts across design stages.

Explore this flow
 02

Post-layout & metal-only ECO

Map patch logic to available spare cells when post-layout changes must stay within metal layers.

Explore this flow
 03

DFT-aware ECO

Account for test constraints and scan connectivity alongside functional correctness.
