When a functional ECO is required, and it pertains to a specific sub-module, the design team aims to restrict the ECO to that particular sub-module rather than initiating synthesis for the entire design.

Performing a complete top-level netlist synthesis can be time-consuming. GOF provides APIs enabling the integration of newly synthesized sub-modules into the original pre-layout netlist, along with updates to the top-level SVF file.

In some cases, there are designs where only INV, MUX, and Flop types are available as spare gates. However, mapping random ECO logic to MUX-only logic can be a challenge for the synthesis engine. Thankfully, GOF offers a solution to this issue.
