PANDA: An LLM-Enhanced Performance-Driven Analog Design Framework Bridging Design Intent and Layout Generation

PANDA is a new LLM-enhanced framework designed for analog circuit design, which integrates high-level design intent with layout generation by managing dependencies across various design stages. It features guided topology synthesis, substructure-aware sizing, and constraint-driven layout generation, significantly reducing design turnaround time from days to hours while enhancing performance. This approach represents a shift from traditional automation methods to intent-centric co-design, offering practitioners a more efficient tool for analog circuit development.
