218 TargetLinkProduction Code Generation Software / 2011 TargetLink® Automatic production code generator Highlights n High-quality production code generation directly from Simulink®/Statefl ow® n Built-in simulation and testing n AUTOSAR support n Certifi ed for IEC 61508 and ISO 26262 n NEW: TargetLink 3.2 (p. 221) n NEW: TargetLink Product Support Center (p. 221) Application Area Model-based design has become the established develop- ment method across many industries. And production code generation is the logical step for turning models into effi cient, production ready code. TargetLink is a software system that generates production code (C code) straight from the MAT- LAB®/Simulink/Statefl ow graphical development environment. Code generation options range from plain ANSI C code to optimized fi xed- or fl oating-point code for certain proces- sors. Versatile code confi guration options ensure that the production code copes with processor constraints. Key Benefi ts Converting graphical models directly into production code ensures perfect consistency between model and code at all times. Since the same model will always result in the same proven code, TargetLink’s code generation is deterministic and thus guarantees the highest software quality. Every step can be tested against the specifi cation via the built-in simulation features. This allows early verifi cation and trans- lates directly into cost reduction, for example, by avoiding expensive ECU software defects. Effi cient Coding Effi ciency is the key to production-quality code. Effi cient code means that a minimum of execution time and resources is required to run the code on a cost-effi cient embedded processor. Code generated by TargetLink is proven to be as effi cient as handwritten code. Other factors also make TargetLink such a useful tool: code readability, traceable model/code dependency, and last but not least, the ability to generate optimized code for specifi c target microcon- trollers. Seamless Tool Chain TargetLink seamlessly connects function development and code generation for the control unit or prototyp- ing hardware. Moreover, it closes the gap between the design and verifi cation phases by automatic means. This provides transparent and defi ned development processes for conventional and AUTOSAR ECUs. Calibration fi les, AUTOSAR software component descriptions, and compre- hensive documentation are generated in addition to the production code.

Typical Steps in Generating Production Code This diagram illustrates the workfl ow between model design and code implementation. It also shows that code verifi cation based on simulation is an iterative process. The workfl ow is shown in greater detail on the following pages. Catalog 2011 • dSPACE GmbH • Rathenaustraße 26 • 33102 Paderborn • Germany • info@dspace.de • www.dspace.com TargetLink 225 Production Code Generation Software / 2011 In tr od uc tio n Ap pl ic at io n Fi el ds Sy st em A rc hi te ct ur e Ra pi d Co nt ro l P ro to ty pi ng EC U A ut oc od in g HI L Te st in g En gi ne er in g So ftw ar e Ha rd w ar e Workflow Control Design and Function Prototyping Control design starts with creating a control model in the integrated design environment MATLAB/Simulink/Stateflow. Before production code generation with TargetLink, you could use dSPACE prototyping systems to carry out conve- nient function prototyping and validation of your new ECU control algorithms. Using the TargetLink Block Library To implement the control algorithms in C code, you need the TargetLink block library. TargetLink blocks contain additional data for code generation, such as the scaling information for fixed-point variables, variable classes, variable names etc. A utility automatically replaces your Simulink controller model with blocks from the TargetLink block library. The process is reversible without any data losses. If you already use the free TargetLink Blockset during control design, conversion is not necessary. Model-in-the-Loop Simulation on Host PC Model-in-the-loop simulation (floating-point) serves as a reference for the following steps and provides the minima and maxima of variables as a basis for subsequent fixed- point scaling if desired.

This code efficiency can be increased even further by generating code for a specific compiler/processor combination using a Target Optimization Module (p. 223, p. 241). Verification on Host PC via Software-in-the-Loop Simulation By means of software-in-the-loop simulation on a host PC, you can compare the behavior of the generated code with the reference data achieved in model-in-the-loop simulati- on. TargetLink offers an intelligent graphical user interface, where you can select signal histories of blocks for detailed analysis. Verification on Target Processor via Processor-in-the-Loop Simulation Using the optional Target Simulation Module (p. 222, p. 223), you can execute processor-in-the-loop simulation to verify the generated code on an evaluation board equipped with the same target processor as your final ECU. Successful verifi- cation of processor-in-the-loop simulation with model-in-the- loop simulation and software -in-the-loop simulation ensures the software quality of the generated code.
