A method analyzes RTL code to determine congestion of a logic design without completing a synthesis phase of a chip design process. The method can include receiving RTL code, and identifying a statement in the RTL code. The method can include determining that the statement in the RTL code corresponds to a structured device group in a component library, wherein the structured device group includes logic devices configured to occupy an area in a predefined spatial arrangement and with predetermined connectivity between the logic devices. The method can include determining congestion associated with the structured device group by performing operations including determining a congestion figure. The method can also include providing, based on the congestion figure, an indication of the congestion associated with the structured device group.
