Accelerating
With AUTOSAR
From start to finish –
first steps to AUTOSAR production ECU – with ETAS solutions along the way
In a significant expansion of its AUTOSAR portfolio, ETAS also relies on the ECU-related technical
skills and domain-specific expertise of the Bosch Group. In the area of model-based development of
AUTOSAR-conformant ECU software, ETAS tools and basic software support a multitude of tasks.
The consistent openness of ETAS AUTOSAR solutions facilitates their easy integration into existing
development environments.
Besides the established, AUTOSARconformant
development tools for
automotive embedded software –
such as ASCET and INTECRIO – ETAS
offers a comprehensive portfolio of
AUTOSAR-conformant authoring and
configuration tools, basic software
and services for the development of
AUTOSAR-conformant projects.
AUTOSAR architecture tool
With the AUTOSAR authoring tool
from ETAS (working title ISOLAR-A),
a cutting-edge architecture tool has
become available that helps meet
many demands for the seamless
collaboration between OEMs and
software and/or ECU manufacturers.
OEM-typical tasks, such as the design,
visualization, and validation of an

entire vehicle system, as well as the
definition of functionalities and communications
relationships between
the software components, comprise
typical requirements for a modern
AUTOSAR architecture tool. As part
of their contribution, suppliers and/
or OEMs ensure the availability of
software components in a manner
commensurate with the respective
vehicle domain. The inclusion of
suppliers aids the cooperation both in
this early phase and in the case of
subsequent modifications.
Quite often, the partitioning of the
system into individual ECUs and
networks is directed by the OEM. It
may, however, also occur in close
coordination with the ECU manufac-
turers. This gives rise to additional
demands the tool must meet. During
this phase, all major demands imposed
by the overall system on networks,
individual ECUs and manufacturers
are specified. The result is a
design specification for each ECU
manufacturer that is more explicit
than any textual description.
Aside from the OEM’s top-down
specifications with the suppliers, the
tool-based cooperation provides the
benefits of improved bottom-up
support, which allows modifications
occasioned by ECU integration to
flow back into the OEM’s overall
system without hindrance. In this
way, a tool such as ISOLAR-A facilitates
not only system partitioning
and early validation of the overall system
but also the consistent consideration
of subsequent changes.
However, AUTOSAR standardization
notwithstanding, still needed are
shared open interfaces that would
allow the tools to be deployed in a
variety of development environments.
The tool ISOLAR-A therefore builds
strictly upon the AUTOSAR Tool Platform
Artop, skirts proprietary solutions
or databases, and can be easily
integrated and operated in any desirable
file-based environments and
software configuration and version
management system (SCM). Artop
also allows the flexible augmentation
of customer-specific development
setups.
Modeling and code generation tool
For many years, the ASCET product
family name has been synonymous
with highly efficient, safe modelbased
software development, and
the high-quality, automatic generation
of production code that is certified
as per IEC 61508 and ISO/DIS
26262. Deployed all over the world,
ASCET meets specific auto industry
demands. These address the development
of complex, hard real-time
capable embedded software that is
memory-optimized for the attendant
hardware. On the other hand, they
stipulate development safety and
processes.
The use of ASCET V6.1 permits
the direct application of individual

THE CHALLENGE
The AUTOSAR-conformant development
of electronic control
units needs to overcome numerous
hurdles.
THE SOLUTION
ETAS offers a consistent AUTOSARconformant
tool chain, which is
successfully deployed in systems
design from simulation to prototyping
to series production ECU.
In addition, ETAS supplies CUBAS,
the complete and proven AUTOSAR
Basic Software. The portfolio is
augmented by competent services
in the AUTOSAR area, e.g., for
consulting and specific project
support.
THE BENEFIT
The powerful AUTOSAR solutions
from ETAS provide consistent
support from initial steps to the
completed AUTOSAR production
ECU.

AUTOSAR- and ASCET-specific
modeling concepts are fully integrated
in the development user interface
and can be used concurrently.
In this way, the easy migration of
existing models into an AUTOSAR-oriented
software architecture is
comfortably supported. From these
AUTOSAR Software Components

C code components and

Basic software plus configuration and

For many years, ETAS has been collecting
an immense knowledge related
to automotive operating systems.
These experiences are reflected
in both the AUTOSAR operating
system RTA-OS and the real-time environment
RTA-RTE. Complemented

Optimized for memory usage and

numerous projects, the CUBAS modules
are being further developed in
accordance with the AUTOSAR
roadmap. The configuration of the
ECU basic software can be effected
by means of another tool called
ISOLAR-B. It accomplishes this purpose
by making use of the AUTOSAR
ECU Extract provided by ISOLAR-A.
