The Naja project offers an open-source Structural Netlist API designed to streamline post-synthesis Electronic Design Automation (EDA) workflows. This presentation will explore Naja’s Python API, which facilitates efficient netlist editing, optimization, and netlist data collection. The talk will showcase the API and will show examples of performing Engineering Change Orders (ECOs) and netlist simplifications, such as constant propagation and dead logic elimination.
