  Circuit topology generation plays a crucial role in the design of electronic
circuits, influencing the fundamental functionality of the circuit. In this
paper, we introduce CIRCUITSYNTH, a novel approach that harnesses LLMs to
facilitate the automated synthesis of valid circuit topologies. With a dataset
comprising both valid and invalid circuit configurations, CIRCUITSYNTH employs
a sophisticated two-phase methodology, comprising Circuit Topology Generation
and Circuit Topology Refinement. Experimental results demonstrate the
effectiveness of CIRCUITSYNTH compared to various fine-tuned LLM variants. Our
approach lays the foundation for future research aimed at enhancing circuit
efficiency and specifying output voltage, thus enabling the automated
generation of circuit topologies with improved performance and adherence to
design requirements.
