Method for modifying models for generating source code

A method for transferring changes between block diagrams comprising cyclically calculated models of blocks connected to signals, wherein a basic model comprises one or more basic blocks, wherein a basic block comprises one or more basic parameters, wherein an extension model comprises one or more basic blocks and at least one extension block, wherein an extension block comprises one or more parameters for code generation, wherein a first block diagram comprises an extension model in a first version, wherein a second block diagram comprises a basic model in a first version, wherein a third block diagram comprises an extension model in a second version, and wherein the first version is older than the second version, wherein the method comprises:

• applying at least one inverted transformation rule to the third block diagram to obtain a first intermediate model, wherein a transformation rule comprises a rule for identifying blocks and a change to be applied to recognized blocks, wherein according to a transformation rule, at least one extension block is inserted and/or at least one basic block is deleted, wherein an inverted transformation rule reverses the change of the assigned transformation rule;
• comparing the first intermediate model with the second block diagram to determine changed basic blocks and/or basic parameters;
• transferring the determined changes to the first block diagram to obtain a second intermediate model;
• and
• applying at least one transformation rule to the second intermediate model to obtain a fourth block diagram;
• wherein two or more stored configuration rules are compared to find commonalities to obtain a generalized configuration rule, and wherein the generalized configuration rule is displayed in an operating interface which enables editing, approving or discarding of the generalized configuration rule, the generalized configuration rule being stored in the case of editing or approving.

A non-transitory computer-readable medium having processor-executable instructions stored thereon for transferring changes between block diagrams comprising cyclically calculated models of blocks connected to signals, wherein a basic model comprises one or more basic blocks, wherein a basic block comprises one or more basic parameters, wherein an extension model comprises one or more basic blocks and at least one extension block, wherein an extension block comprises one or more parameters for code generation, wherein a first block diagram comprises a basic model in a first version, wherein a second block diagram comprises an extension model resulting from the basic model of the first version, wherein a third block diagram comprises a basic model in a second version, and wherein the first version is older than the second version, wherein the processor-executable instructions, when executed, facilitate:

• 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;
• wherein two or more stored configuration rules are compared to find commonalities to obtain a generalized configuration rule, and wherein the generalized configuration rule is displayed in an operating interface which enables editing, approving or discarding of the generalized configuration rule, the generalized configuration rule being stored in the case of editing or approving.
