A layout of an integrated electrical circuit on a memory unit of a computer system includes one or more instantiations of at least one circuit network description as well as information about the instantiations. A raw data structure represents the logical configuration of the layout and associates each instantiation with one, and only one, polygon data structure. A modified data structure is produced to represent the layout, which associates a circuit network description with one, and only one, polygon data structure, wherein the geometrical differences between the instantiations of this circuit network description are taken into account by variants in the polygon data structure.
