Saber for Automotive Systems 

Saber Accelerates Robust Design 

Successful automotive designs require systematic methods to meet aggressive performance goals and compressed schedules. Saber is used to design and verify the interaction of multiple technologies (electrical, mechanical, hydraulic, magnetic, software, etc.). Designers create virtual prototypes of the system, including the wire harness, to reduce the number of design iterations and hardware prototypes. Far more tests and design variations are possible in this environment compared to hardware prototyping. Through a Robust Design methodology, system performance is immunized against variance in parameters. These methods have proven to reduce design cycle time and maximize performance and reliability.

Vehicle Power Network
As electronic content in vehicles increases, so do the challenges in meeting this rising energy demand on the power network. Designers must create efficient power generation and distribution systems that perform with flawless reliability.

Design teams use Robust Design methodologies to manage complex energy generation and distribution problems, such as designing an alternator charging system or taking into account system and environmental variations that affect performance. Saber’s comprehensive simulation, modeling resources, and analysis capabilities enable design teams to deploy Robust Design methods to meet the challenges of powernet design.

Saber Advantages
  • Accurately size system components to match energy generation with corresponding consumption
  • Eliminate surprises in power network loading and distribution through early verification
  • Test the complete system earlier with hardware/software co-simulation
  • Save time and eliminate errors with industry-proven power model libraries
  • Enable design portability using industry standard VHDL-AMS and MAST languages
  • Maximize reliability with advanced sensitivity, statistical, and fault analyses
  • Increase analysis throughput with distributed simulations across multiple CPUs

In-vehicle Networks (IVN)
Advances in automotive design have been propelled by dramatic increases in electronic systems content. Numerous electronic systems must communicate with each other over a complex network which often contains multiple communication protocols, such as CAN, LIN, and FlexRay standards. These complexities add significant challenges to verifying the physical network layer.

With a traditional prototyping approach it is impossible to build enough prototypes to adequately test even the most important variations of a network design. Virtual prototyping through simulation has become the proven solution for verifying data network reliability. Saber provides the comprehensive simulation and analyses capabilities needed to apply Robust Design methodologies to in-vehicle networks and ensure reliability.

Powertrain & Hybrid-Electric Vehicle (HEV/EV) Systems
Reliable vehicle operation depends on successful integration and verification of all drivetrain component interactions under varying operational and environmental conditions. Given the extraordinary complex nature of hardware and software controls in drivetrain design, engineers use Robust Design methods to characterize and verify the interaction of mechatronic systems. Saber’s comprehensive modeling, simulation, and analysis capabilities are applied to improve system performance, reduce cost, and maximize reliability of these critical systems.

Wire Harness Design & Simulation
The wire harness forms the backbone of the entire electrical system of automotive and aerospace vehicles. The correct and reliable implementation of the wire harness represents one of the most expensive and technically challenging aspects of vehicle systems design. Saber Harness provides proven design and verification capabilities in conjunction with the Saber Simulator to create correct-by-design wire harnesses. Designers can create schematic drawings and connectivity diagrams, export component and wire data, import geometry information from MCAD tools, simulate electrical functions, create bundles with connector positions and generate data for manufacturing – all within an easy-to-use design tool.
