US 2019/0163452 A1 · METHOD AND SYSTEM FOR GENERATING PROGRAM CODE

Abstract

A method for generating program code based on one or more blocks of a block diagram in a technical computing environment, an identifier being assigned to at least one, preferably each, of the one or more blocks of the block diagram. A processor opens the block diagram in the model editor, converts the block diagram to an intermediate representation using the code generator, wherein the conversion comprises checking if a replacement condition is fulfilled for a current block in the block diagram. Checking the replacement condition includes verifying that a predefined functional code unit is assigned to the identifier of the current block, in that case changing the block to a placeholder containing input/output-definitions but no functionality. The processor then converts the intermediate representation to program code, the conversion comprising adding a predefined functional code unit from the data definition tool to the definition code corresponding to the placeholder block.

A method for generating program code based on one or more blocks of a block diagram in a technical computing environment, an identifier being assigned to at least one or each of the one or more blocks of the block diagram, the technical computing environment comprising a model editor, a data definition tool and a code generator, the data definition tool comprising at least one functional code unit and a corresponding identifier, the technical computing environment being executed by at least one processor of a host computer, the method comprising:

opening the block diagram in the model editor;
converting the block diagram to an intermediate representation using the code generator;
checking if a replacement condition is fulfilled for a current block in the block diagram, the checking of the replacement condition comprising verifying that a functional code unit is assigned to the identifier of the current block;
replacing the current block by a placeholder containing input/output-definitions but no functionality when the replacement condition is fulfilled;
and
converting the intermediate representation to program code and adding the functional code unit assigned to the identifier of the current block from the data definition tool to a definition code that corresponds to the placeholder.
