Abstract: A method for editing a computer-aided design model for developing electronic control units in a design environment, whereby the design model comprises at least one model object with first data. The method begins with the reading of all model objects of the design model and the reading of an allocation list, which assigns a particular globally unique key to each model object. If the first data are available, the reading of the first data from a first memory location follows. Then, assignment of the first data to the model object based on the globally unique key occurs, so that the first data are available during editing of the design model. If the first data are not available, assignment of the globally unique key to the model object occurs, so that the globally unique key is available during tediting of the design model.

Abstract: A method for the computer-aided generation of at least one part of an executable control program, particularly a measuring, control, regulating, and/or calibration program, for controlling a control system having at least one electronic processor unit is provided. The functionality of the control program is described at least partially in at least one graphical model and the graphical model is divided in hierarchical levels into submodels. A submodel can be divided nested into submodels of a lower hierarchical level, whereby values for options for the compiling of the graphical model to program code are preset and program code is generated from the model co-compiled to the executable control program. Values for options for the compiling of the graphical model to program code and to the executable control program can be preset thereby granularly with the automatic avoidance of conflicting presettings of values for these options.
