1. A method for changing a configuration of a programmable logic module, the method comprising: reading in an initial configuration of the programmable logic module, so that a logic description is available for at least a portion of the initial configuration, creating a logic description of a target configuration, the creating comprising: changing one or more logic elements and/or connection elements from the logic description of the initial configuration, adding one or more logic elements to the target configuration, and determining transfer points using assignment information, wherein the transfer points comprise logic elements present in the target configuration and the initial configuration, said logic elements including registers or drivers, marking as free unused logic elements of the initial configuration, placing the added one or more logic elements of the target configuration on any logic elements marked as free, connecting the added one or more logic elements of the target configuration to the transfer points via unused connection elements, creating a changed bit stream from the logic description of the target configuration, and writing the changed bit stream to the programmable logic module.
