Abstract—Optimization-based analog layout automation does not yet find evident acceptance in the industry due to the complexity of the design problem. This paper presents a Self-organized Wiring and Arrangement of Responsive Modules (SWARM), able to consider crucial design constraints both implicitly and explicitly. The flexibility of algorithmic methods and the expert knowledge captured in PCells combine into a flow of supervised module interaction. This novel approach targets the creation of constraint-compliant layout blocks which fit into a specified zone. Provoking a synergetic self-organization, even optimal layout solutions can emerge from the interaction. Various examples depict the power of that new concept and the potential for future developments.
