Abstract: A method for generating analog schematic diagram based on building block classification and reinforcement learning is disclosed. First of all, deeper relationship features among devices with building block classification are obtained. Secondly, the device leveling gives an initial device placement topology resulting from the current/signal flows in the circuit netlist. Thirdly, reinforcement learning is applied to refine placement and routing topologies by embedding the building blocks and current/signal flow information into feature vectors. Pattern routing and maze routing algorithms are performed for local and global interconnections, respectively, followed by placement adjustment for density balancing and space minimization to obtain aesthetic analog circuit schematics.
