  • Publication number: 20250068821
    Abstract: Methods and systems for circuit generation include generating a circuit design. Paths are extracted from the circuit design, with the paths representing sequences of connected circuit components from one terminal of the circuit to another. The extracted paths are embedded as respective vectors in a latent space. A property of the circuit design is determined using an ensemble of trained surrogate models that accept a sequence of the vectors as input.
