  • Patent number: 5267176
    Abstract: Method for placing modules on a carrier. Modules, for example cells, are placed on a carrier, for example a chip, with the method. For placement, the modules are arranged such on the placement region of the carrier that the center of gravity of the modules falls onto the center coordinates of the placement region (global placement S1). Subsequently, the placement region is partitioned into sub-regions, modules are allocated to the sub-regions and the area of the sub-regions is defined in the ratio of the area of the modules allocated to these sub-regions (partitioning, S2). In the next step, a global placement is again carried out, i.e. the modules are arranged such in the sub-regions that the modules allocated to the sub-regions have their center of gravity falling onto the center coordinates of these sub-regions. The steps of global placement and of partitioning follow one another until only at most k modules are still present per sub-region.
