Why Model? SystemVision for System Integration,
Simulation & Analysis
Model Driven Development (MDD) enables a modeling
and simulation platform for virtual integration of diverse The SystemVision multi-discipline design environment
technologies. was specifically designed to allow fluent design and
simulation of complex systems in a single simulation
• Modeling facilitates moving full platform-component, environment. With SystemVision, engineers enjoy a
subsystem, and HW/SW integration early in the modeling environment that can simultaneously handle all
product life cycle, reducing risk aspects of system design.
• Synthesis/automation allows exploration of full
platform design options, leading to better design
performance and/or lower cost
• Platform-independent, domain-specific modeling
allows separation of engineering domains, but with
abstraction of models to allow communication and
collaboration across domains
• Modeling allows designers to pull different design
flows together into a coordinated, integration
system, even if he/she is not familiar with a model
outside of his/her own domain
• Modeling improves chances for finding and fixing
problems early, saving time and money
SystemVision integrates models of mixed analog/digital
circuits; thermal, mechanical and hydraulic systems;
and continuous and sampled-data control systems. It
provides for the fluent, multi-level model integration
required for true systems design and analysis. It
combines math-based analysis with analog and digital
An MDD methodology manages the process from circuit simulation, without using choice-limiting,
concept exploration and acceptance to full-scale proprietary formats. Joining high-level behavioral
development, breaking the system integration models with lower-level device models in a multi-
bottleneck. disciplined environment allows for rapid examination of
design tradeoffs.
• Use models to drive the design process
• Create models to capture the design phase • Reduce development time
• Use models to validate requirements, design • Simplify HW/SW integration
• Transform models from one view to the next • Promote design reuse
• Reduce manufacturing & warrant costs
SystemVision, an intuitive virtual-prototyping design environment, allows full verification of successive design stages: From the
Functional stage, where an executable specification can be defined and tested, through the Architectural stage, where functions
are partitioned, to the Implementation stage, where the final system SW/HW is integrated and tested on a virtual target platform.
SystemVision SVX BridgePoint Executable, Translatable
UML Suite
SystemVision SVX is a virtual execution environment for
developing, unifying, and verifying sophisticated multi- BridgePoint is a comprehensive design environment

The SVX client-server architecture provides for precise,
distributed, time-synchronized interfaces between
signal generators and consumers. These interfaces
are easily placed, as symbols, in graphical tools such
as SystemVision, Simulink, and LabVIEW. In addition,
a C/C++ API makes it easy for application embedded
software to interact with models of control systems,
multi-physics subsystems, sensors & actuators, and
analog & digital electronics.
SVX Packaging Options
• SystemVision SVX client for SystemVision
BridgePoint xtUML tools enable engineers to develop,
model, and test their concepts in a platform-independent
environment before the target hardware is built. This
allows important design decisions to be made early… and
correctly.
• Work at a more powerful level of abstraction to write
more code in less time. Solve problems more easily
by dealing with fewer irrelevant details.
• Test ideas quickly. Since the models can be executed
independent of hardware/system software details,
you can test concepts without having to bind yourself
• SystemVision SVX client for Simulink
to an unresolved platform.
• SystemVision SVX client for LabVIEW
Graphical Models Increase Understanding
• SystemVision SVX client for SystemC
Diagrams expose abstraction, which allows us to reason
• SystemVision SVX client for C/C++
about their correctness. The views in BridgePoint
• SystemVision SVX client for Java
are concise enough to be understood by all project
• SystemVision SVX client for xtUML stakeholders, including non-technical personnel.
• SVX Application Server for multi-client and
The design process begins with a system-level overview
multicomputer application signal routing
in which the system is partitioned into components and
their interfaces. These components, in turn, contain the
behaviors of specific elements that further describe
the design. The models are reusable and platform-
independent. All of the fundamental BridgePoint building
blocks (class diagrams, state machines, action language,
etc.) enable fast and accurate development, executable
models, and 100% translatable output.

Virtual System Integrator
Designers need a software evaluation tool that can
deliver the same actions and reactions as the planned
hardware environment. The Mentor Graphics Virtual
System Integrator (VSI) is that tool. VSI is a software
validation environment that behaves like an integrated
system made up of hardware elements such as electronic
control units (ECU), buses, sensors, and actuators, etc. It
enables early validation of software functionality before
actual hardware is available.vv
• Supports AUTOSAR “Virtual Functional Bus
simulation” plus RTOS execution at component and With VSI, embedded system software can be verified
runnable levels at any time during the design process, with minimal
hardware system prototyping. The underlying MDD
• Enables early validation of software functionality technology within VSI ensures that embedded code
before actual hardware is available tested therein is ready to become the application.
• Reduces the need for physical prototypes and VSI is part of the comprehensive Volcano Vehicle
testbenches Systems toolset, which provides a robust medium for an
AUTOSAR-based vehicle system design flow, including:
• E/E architectural design
• Application software development
• Virtual validation
• Software test
VSI receives embedded code from the BridgePoint
development tool and system characteristics from
Vehicle System Architect (VSA). VSI creates a virtual bus
to evaluate the SW and HW interactions among these
elements.
