More Information about TargetLink

TargetLink is deeply rooted in the automotive industry. We therefore attach great importance to supporting the relevant standards. Above all, this includes excellent AUTOSAR support, both in terms of workflows and the quality of the generated code. Other standards such as ASAM MCD-2 MC (ASAP2), target support for µCs, support for coding standards such as MISRA-C, and exchange formats such as FMI are also included. We ensure that integration into the vehicle runs smoothly!

Supported Automotive Standards


As a de-facto standard for automotive E/E architectures, AUTOSAR contains specifications for communication interfaces between application functions and basic system functions. The TargetLink AUTOSAR Module makes TargetLink’s modeling, simulation and code generation features available for designing Classic AUTOSAR software components (SWCs). Furthermore, TargetLink 5.0 supports select features of Adaptive AUTOSAR Release 19-03. AUTOSAR Adaptive Platform, also called Adaptive AUTOSAR, is a standard based on a service-oriented architecture that aims at on-demand software updates and high-end functionalities.


Internal ECU variables in measurement and calibration can be defined in the description format ASAM MCD-2 MC. Because a code generator also needs to have close links with calibration systems, TargetLink can export calibration data as ASAM-MCD 2MC file for calibration tools.


The British MISRA C standard (MISRA: Motor Industry Software Reliability Association; is a widely accepted C subset for projects in the automotive industry. Its aim is to define rules for avoiding common software errors that can occur when software engineers write software by hand. Most of these rules also make sense for machine-generated code. TargetLink-generated code complies with the vast majority of MISRA C rules. If deviations from the MISRA C standard are a technical necessity, they are identified and well documented. dSPACE provides detailed documentation about TargetLink’s MISRA C compliance to all TargetLink customers on request. For more information, please contact


The Functional Mock-up Interface (FMI) is an open standard for the tool-independent exchange and integration of plant models that are provided by various tool vendors. Functional Mockup Units (FMUs) can be exported from TargetLink to simulation environments that support FMI.

High-Performance Classic and Adaptive AUTOSAR Support

The optional TargetLink AUTOSAR and Adaptive AUTOSAR Modules make modeling, simulation, and code generation features of TargetLink available for designing Classic and Adaptive AUTOSAR software components.

The TargetLink Classic AUTOSAR block library.

Classic AUTOSAR Support

TargetLink supports the vast majority of Classic AUTOSAR communication mechanisms and generates genuine RTE API function calls.

Modeling Classic AUTOSAR software components

Designing Classic AUTOSAR Software Components

The TargetLink Classic AUTOSAR Block Library provides Classic AUTOSAR structure elements, for example, runnables, ports, and communication interfaces, for modeling purposes. To define a Classic AUTOSAR runnable, a Function block specified as a Classic AUTOSAR runnable is used in a subsystem, similar to regular TargetLink functions.

The TargetLink InPort and OutPort blocks are used to define the data exchange between the runnables of one or more software components. Developers specify properties on the block level and via the TargetLink Data Dictionary.

Generated C code with RTE API function calls, i.e., Rte_IRead(), Rte_Pim(), and Rte_IWrite()

Generating Classic AUTOSAR-Compliant Code

TargetLink generates production code for Classic AUTOSAR software components. Moreover, TargetLink provides special options allowing for Classic AUTOSAR optimizations. Runnables are implemented as C functions, and Classic AUTOSAR communication mechanisms are implemented as RTE API function calls according to the Classic AUTOSAR standard. The same model can be used to generate Classic AUTOSAR-compliant code and standard TargetLink code.

Simulating and Testing Classic AUTOSAR Software Components

TargetLink simulates Classic AUTOSAR software components in all simulation modes. Multiple software components can be simulated in one simulation run. The communication between software components is simulated to the extent supported by the Simulink® design environment. For testing purposes in SIL and PIL simulation mode, TargetLink generates a stub RTE that maps the RTE API function calls in the application with software component code to global variables and generates access functions to global variables.

Example round trip for Classic AUTOSAR development

TargetLink in a Classic AUTOSAR Tool Chain

For Classic AUTOSAR software development, TargetLink is typically combined with an AUTOSAR architecture tool such as SystemDesk. A software architecture with multiple components is specified in the architecture tool, while TargetLink is used to design and implement the individual software components. The two tools exchange data via ARXML files. Both a top-down approach (starting with the software architecture) and a bottom-up approach (starting with a TargetLink function model) can be used for Classic AUTOSAR round trips. This AUTOSAR round trip can be simplified and automated using dSPACE AUTOSAR Compare, which lets you compare and manually or automatically merge your AUTOSAR artifacts.

Modeling Adaptive AUTOSAR event communication with TargetLink

Designing Adaptive AUTOSAR Applications

TargetLink supports the model-based development of functional parts of adaptive applications. It provides different model elements for you to model the functionalities.

The following uses cases are supported to model communication according to ara::com:

  • Accessing fields as a service consumer or service provider.
  • Sending or receiving events.
  • Calling or implementing a method.
  • Modeling and simulating error handling

In addition, TargetLink supports the modeling of persistent data access, i.e., reading and writing key-value pairs from key-value storage, according to ara::per. 

Generating Code for Adaptive Applications

TargetLink generates Adaptive AUTOSAR functions from subsystems specified for Adaptive AUTOSAR. The Adaptive AUTOSAR function is a TargetLink-specific C++ function representing a partial functionality of an adaptive application. This function can be called in the C++ code of an adaptive application.

Simulating and Testing Adaptive AUTOSAR Models

TargetLink simulates Adaptive AUTOSAR models in MIL and SIL simulation mode. While building the simulation application for SIL simulation, TargetLink uses preprocessor macros and conditional compilation. This allows the simulation of the Adaptive AUTOSAR functions directly in TargetLink without the need of Adaptive AUTOSAR middleware. In addition, TargetLink supports modeling error handling during communication as specified by Adaptive AUTOSAR.
