While demand for custom processors is surging, the design process from RTL to physical layout requires highly specialized expertise. This study introduces autonomously operating "Agentic AI" to propose an end-to-end circuit and physical layout generation workflow without human intervention. Within this framework, the AI agent autonomously manages a digital design flow, iterating through circuit construction, functional verification, logic synthesis, place and route, and physical verification. Furthermore, it extracts parasitic components from the layout to perform post-layout simulations, automatically feeding back to the logic synthesis phase for re-optimization if any violations occur. To evaluate this workflow, a demonstration experiment was conducted using the open-source RISC-V core "Ibex" as a baseline. The AI agent successfully designed and integrated a flip-flop-based memory, an SPI controller, and a GPIO controller. Without any human designer intervention, the system achieved completely autonomous layout generation for the entire system, yielding a processor with a layout size of 605 µm × 605 µm and demonstrating the practicality of Agentic AI-driven automation.
