Abstract

A graph-based timing analysis (GBA) is applied to a circuit design that includes a routed gate-level netlist to produce timing estimates of the circuit design. A machine learning (ML) model is applied to modify these GBA timing estimates of the circuit design to make them more accurate. For example, the ML model may be trained using timing estimates from path-based timing analysis as the ground truth, and using features of the circuit design from the GBA as input to the ML model.
