# GOF automatic functional ECO: input checklist

This note summarizes the inputs for GOF’s automatic full-layers functional ECO flow.

## Required inputs

Prepare Liberty libraries, Verilog models for modules absent from those libraries, implementation and reference netlists, and the top module name. Synthesize the reference with the same constraints as the pre-layout netlist. Designs with multibit flops require implementation and reference SVF files.

## Review status

AI summary by Codex of public documentation; no design execution or project validation performed.
