A supply network is designed for a microelectronic circuit by a method for computer-aided design, in that an outline of the microelectronic circuit is detected and the supply network is generated with this outline. In the process, the supply network is designed with a structure in which a pattern is pre-determined and is repeated within the outline of the supply network until the supply network is completely filled up. In addition, a device is disclosed that is configured to carry out the above method.
