1. A method for the computer-aided generation of at least one part of an executable control program for controlling a control system having at least one electronic processor unit, the method comprising: describing a functionality of the control program at least partially in at least one graphical model; dividing the graphical model in hierarchical levels into submodels, a submodel of a hierarchical level being configured to be divided nested into submodels of a lower hierarchical level; providing present values (x) for options (X) for the compiling of the graphical model to program code; generating program code computer-aided with consideration of the values (x) of the options (X) from the model; and co-compiling the program code to the executable control program, wherein a value (x j ) for an option (X) for the compiling of the graphical model for at least two nested submodels of different hierarchical levels are preset, and the values (x j ) for the options (X) are taken into account in the computer-aided generation of program code for each submodel, and wherein an option (X) of the submodel, said option not provided with a value (x j ), at the lower hierarchical level assumes the value (x j ) of the corresponding option (X) of the submodel at the higher hierarchical level.
