E/E Architecture
Design and Evaluation
PREEvision Use Case
E/E Architecture PREEvision
PREEvision offers comprehensive functions for the model-based design of electric/electronic
architectures and the fast design and evaluation of architecture alternatives.
PREEvision Advantages
> Architecture designs verified early on
> Reduced expenses and short
development duration
> High initial quality for series
development
> Consistent and integrated modeling,
from systems design to wiring
harness design
> Multi-dimensional comparison of
architectures according to customizable
criteria, such as cost, weight, installa-
tion space, bus-load, etc.
> Traceability from requirements through
all layers including the wiring harness
PREEvision supports the design of E/E ar-
chitectures across all relevant technical lay-
ers. The abstraction layers extend from the
logical architecture, through the software
architecture and hardware architecture, to
the hardware geometry. Data available from
other tools can be imported and thus easily
amalgamated in a model. Signal and wiring
harness routers and automatic consistency
checks accelerate development and ensure
consistent modeling.
Factors for Success at a Glance
To develop a cost-optimized and robust E/E
system, PREEvision enables the easy evaluati-
on of architecture alternatives, even during
early development phases. The success fac-
tors of an architecture can be determined by
architects themselves. In addition to impor-
tant optimizations for the overall vehicle, such
as weight, costs, installation space, cable
length and power consumption, PREEvision
also takes E/E system-relevant targets into
account, such as the bus-load and timing or
security requirements.
It is also possible to compare an architecture in different
vehicle variants of a product line. Finally, the architect deci-
des which factors for success are taken into account.
Multi-Dimensional Decision Network
A multi-dimensional decision network can be laid out for
evaluation of the architectural design, and thus an architec-
ture can be evaluated in comparison to other alternatives.
The data model holds information required for quantitati-
ve evaluation and from this, weight or bus-load, for examp-
le, may be calculated.
PREEvision provides the UML-based SOA diagram for service-oriented
architecture development.
Architectures are easy to compare with PREEvision. Criteria for success can be freely defined by the architect, and the status quo can be read out in
reports at any time based on the current model data.
Metric Framework
The parameters for benchmarking of alternative architec-
ture designs are calculated with metrics. PREEvision fea-
tures a host of included metrics which can be enhanced by
the customer. The metrics are implemented with Java pro-
gramming language. Metric blocks are a component of the
graphical metric language. Metrics used within the metric
framework are always run against the current model data.
They can be calculated using the overall model or a previ-
ously selected variant.
The results of the performance comparison provide
architects with a basis for making decisions on determining
the architectural design. They provide important informati-
on for the refinement of the architecture during the deve-
lopment process. Thanks to the comprehensive data
model, the finalized architecture model can be used as the
basis for further development of the E/E system.
