Q: Are there any real-world examples of results
achieved through this approach?
Sandmann: IAV, an engineering company that works
with OEMs such as the Volkswagen Group, has said that Simulink and
Embedded Coder enabled them to automatically generate
AUTOSAR-compliant C-code and other AUTOSAR artifacts. They recently
presented an AUTOSAR project for a Drive-Select application that is
on the road with the new AUDI A3 (here’s a link to the presentation,
for reference: MathWorks Automotive Conference 2012-Presentation).
Q: What’s the best strategy for OEMs, suppliers,
and other parties to work on standards such as AUTOSAR?
Sandmann: The best strategy is to adopt Model-Based
Design for production code generation to reduce development time and
increase product quality. What these engineers need is tool chain
that supports AUTOSAR and enables iterative development across all
phases of production ECU projects, which typically cannot strictly
use a “top-down” or “bottom-up” development workflow. AUTOSAR
fits seamlessly into this development paradigm and complements the
goals of addressing challenges resulting from increasing complexity
of the automotive applications and higher time-to-market pressure.
Today, high-level design tools have progressed to a stage where they
can help engineers import and export AUTOSAR Software Component
descriptions and generate AUTOSAR production code in one integrated,
round-trip environment. What is notable with Simulink, is that it
supports AUTOSAR using model configuration settings rather than
AUTOSAR-specific blocks. As a result, a single model can be used as
a golden reference for simulation, rapid prototyping, and production
code generation in both AUTOSAR and non-AUTOSAR environments,
facilitating software reuse. By using Model-Based Design in their
AUTOSAR projects, automotive design engineers are able to focus on
developing software component functionality, instead of getting
bogged down with ATUOSAR implementation details.
