This project follows classical technique for code generation from Simulink models for an embedded system application. Commercially available tools for code generation are Embedded Coder from Mathworks and TargetLink from dSpace. Flex and Bison are used in this project for code generation. Flex and bison are widely used code-generation tools and are free. Model parser generated from Flex and Bison has the capability to parse model file and extract all the information related to blocks and lines.

Simulink PLC Coder generates hardware-independent IEC 61131-3 Structured Text from Simulink. To start using Simulink PLC Coder. Download a free trial.

Simulink PLC Coder™ generates hardware-independent IEC 61131-3 Structured Text and Ladder Diagrams from Simulink ® models, Stateflow ® charts, and MATLAB ® functions. The Structured Text and Ladder Diagrams are generated in PLCopen XML and other file formats supported by widely used integrated development environments (IDEs) including 3S-Smart Software Solutions CODESYS, Rockwell Automation Studio 5000, Siemens TIA Portal, and Omron Sysmac Studio. As a result, you can compile and deploy your application to numerous programmable logic controller (PLC) and programmable automation controller (PAC) devices. Simulink PLC Coder generates test benches that help you verify the Structured Text and Ladder Diagrams using PLC and PAC IDEs and simulation tools. It also provides code generation reports with static code metrics and bidirectional traceability between model and code.

Support for industry standards is available through.
