In general, automatic layout composition techniques based on pre-designed devices facilitate the production of small IC numbers by prefabricating their basic structures. They also enables a high degree of automatic layout synthesis. However, for their correct electrical behavior it is essential, that potential problems caused by electro-magnetic compatibility (EMC) are fully considered during the design phase. This paper presents a new concept for generating analog layout components by combining module generators, known from digital technology, with a flexible guidance scheme driven by the structural synthesis of the analog circuit. By utilizing both pre-defined functional blocks and flexible analog interconnection methods our approach takes EMC problems fully into consideration. The layout concept introduced here has successfully been applied to different sample circuits.
