Automobiles began to come under electronic control decades ago with the advent of Electronic Control Units (ECU) that managed basic engine functions. Over the years these modules proliferated within vehicles of all types, to the point where today’s autos, trucks, and tractors may incorporate dozens of modules overseeing functions as diverse as fuel injection and heated seats.

To contend with the rapid growth of electronic content, manufacturers must manage complexity, employ more automation in design processes, and achieve faster, more reliable system integration and component design. Automation and verification of hardware, software and mechatronics systems must go beyond mere ECU design automation and focus on interactions between hardware, software and the network connecting the platform components and systems.

An additional side effect of increasing complexity is the growing reliance on software to support differentiating product features. Improved automation is also needed in the design of electrical, electronic and embedded software components, which require a stable and reliable software development environment for modeling, simulation, verification and testing of software interfaced to actual hardware.

Why Use SystemVision and BridgePoint?

The Design Process Begins with a System-Wide View

The SystemVision modeling environment addresses the functional, architectural, and implementation levels of the vehicle design process, accounting for every aspect of the underlying system design:

  • Application and platform software
  • Sensors, actuators, and motors
  • Digital and analog electronic elements (including mixed-signal)

Combining high-level behavioral models with lower-level device models in a multi-disciplined environment, SystemVision ensures fast, reliable prototyping and evaluation of design decisions. Engineers can quickly and easily create and analyze designs that include levels of abstraction from math-based behavior down to circuit implementations. Modeling technology enables designers to grasp complex project challenges and keep pace with changing, evolving systems.

Modeling Methods Take Aim at Embedded Software Complexity

Executable models:

  • Allow testing and verification of a system before hardware platform is available
  • Enable removal of defects early in the cycle

BridgePoint facilitates the creation of high quality, regular code that represents both the software and hardware portions of a design, improving productivity through executable UML models and open, flexible, repeatable code generation. Using BridgePoint, requirements can be refined and validated through the use of executable models. BridgePoint gives its users the tools to model full-system requirements and drive the downstream design flow.

Model Driven Development - Mentor Graphics

A virtual prototyping infrastructure in which models from different domains can be integrated at each stage of the development life cycle allows system integration issues to be identified and addressed earlier, helping reduce overall program time and cost.


System Modeling - Industries - Mentor Graphics

System modeling tools from Mentor Graphics allow models from different domains to be integrated at each phase of the design flow, allowing system integration issues to be identified and addressed earlier, and helping to reduce overall program time and costs in the design of complex medical electronic devices.


Medical Systems - Mentor Graphics

A multi-discipline development environment and concurrent design methodology provide continuity throughout the design, implementation, and validation phases of system development. Hardware and software development progresses in-sync, ensuring that changes in one development flow can immediately be analyzed for effects in complementary flows.


System Modeling - Mentor Graphics

Virtual system integration can take place at the time of system requirements definition or during preliminary or detailed design, allowing critical problems to be uncovered well before final system integration. True system modeling provides an interactive environment in which designers can verify their specific part of an overall puzzle, a puzzle in which any small change can affect the final outcome.


Model-Driven Systems Development for Mil/Aero Industries

Designers can use model-driven system development to test and verify their complex system designs to be compatible with harsh operating environments and compliant with strict reliability requirements. You can avoid cost overruns, schedule delays, low reliability, and even product failures related to the development of large-scale systems and platforms.
