A computer-implemented method generates program code of an executable control program for controlling a control system. Functionality of the control program is described at least in part in a graphical model. The graphical model is translated into program code in a text-based programming language. The method includes: generating a first placeholder representing a variable, the first placeholder being used in a predetermined segment of the program code; generating a second placeholder, which is placed before a beginning of the predetermined segment of the program code that uses the first placeholder; and generating a third placeholder, which is placed after an end of the predetermined segment of the program code that uses the first placeholder.

Method for generating program code, method for configuring a control unit and computer system

A method for generating source code from one or more blocks of a block diagram that comprises at least two non-virtual blocks and at least one signal link between two non-virtual blocks includes: transforming the block diagram into an intermediate representation, wherein transforming the block diagram into the intermediate representation comprises transforming a first block having access to a multi-component variable; successively optimizing the intermediate representation; and translating the optimized intermediate representation into source code. Transforming the first block comprises: testing whether a block pair made up of the first block and an adjacent block comprises an equal assignment; and removing any assignments in which a reference to the same variable exists on both sides.

Method for generating source code

Source code is generated from one or a plurality of blocks of a block diagram. The block diagram is hierarchical and includes at least a first subsystem that is configured for an incremental code generation. The block diagram references a definition database which includes a first object. The method for generating the source code includes: opening, by a computer system, the block diagram including the first subsystem in a model editor; generating, by the computer system, source code for the first subsystem, wherein generating the source code for the first subsystem includes determining information about the first subsystem; storing, by the computer system, the information about the first subsystem in the first object; and generating, by the computer system, source code for the block diagram, wherein the first object is read out to influence at least one parameter for generating the source code for the block diagram.

Incremental code generation method

A method for generating source code from one or more blocks of a block diagram includes: generating the block diagram; determining whether the descriptors of first and second block variables are concordant or different and whether or not first and second blocks are located in the same region; and implementing the first and second block variables as a single variable or as two separate variables in the source code based on the determination of whether the descriptors of the first and second block variables are concordant or different and whether or not the first and second blocks are located in the same region. The first and second block variables are implemented in the source code as a single variable if the descriptors of the first and second block variables are concordant and the first and second blocks are located in the same region.

A method for transferring changes between block diagrams having cyclically calculated models of blocks connected to signals includes: applying a plurality of transformation rules to the first block diagram to obtain a first intermediate model, wherein a transformation rule includes a rule for identifying blocks and a change to be applied to recognized blocks, wherein at least one extension block is inserted and/or at least one basic block is deleted; comparing the second block diagram to the first intermediate model; determining at least one configuration rule from the comparison, a configuration rule comprising a rule for identifying a block or parameter and a change to be applied to an extension parameter; applying the plurality of transformation rules to the third block diagram to obtain a second intermediate model; and applying the at least one configuration rule to the second intermediate model to obtain a fourth block diagram.

Method for modifying models for generating source code

A computer-implemented method for generating program code based on one or more blocks of a block diagram in a technical computing environment including a model editor and a code generator. The method comprises opening the block diagram in the model editor, the block diagram comprising a delay block that delays a signal received by an input port for a number of periods before being emitted at an output port, determining that a composite signal is connected to the input port, and generating definitions for variables, the variables including a state buffer, a pointer and an index. The method further comprises generating loop code, the loop code comprising instructions for setting the pointer to a position in the state buffer with an offset of index, instructions for outputting elements from the state buffer, instructions for inputting the composite signal to the state buffer, and instructions for adjusting the index.

Method and system for generating program code

A method for generating production code from a block diagram on a host computer is provided. A block in the block diagram has a number of input ports for receiving signals and a number of output ports for sending signals. The processor identifies a first block in the block diagram. The input signal is traced back to a second block upstream of the first block. Compliance with a optimization condition is checked, the optimization condition being fulfilled when a group of adjacent blocks has an assignment operation that affects one or more elements of the input signal while leaving at least one element of the composite variable unchanged. A combined production code is generated for the group of adjacent blocks when the optimization condition is fulfilled so that the combined production code includes write instructions for those elements of the composite variable that are affected by the assignment operation.

Method and system for automatic code generation

A computer-implemented method for generating control unit program code. The control unit program code or an intermediate representation in the generation of the control unit program code is generated from at least one first data object with at least one first software tool. The first software tool outputs at least one message about the generation process during the generation of the control unit program code or the intermediate representation, and a computer-implemented message management environment acquires the message output by the software tool. The evaluation of the messages output by the software tools during the generation process is achieved in a more effective manner in that a qualification for the acquired message at least as open or approved is acquired by the message management environment and in that a qualification precondition for a message qualified as approved is also acquired by the message management environment.

Computer-implemented method for generating control unit program code and message management environment relating thereto

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.
