Saber Simulation
Alyssa Dipiero
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.
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.
ISO 26262 strongly recommends simulation for system-level and hardware-level verification. SaberRD and SaberES Designer are ISO 26262 certified and support Functional Safety by Fault Effect Analysis.
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.
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.
SaberEXP is a piecewise linear (PWL) quick converging simulator for power electronics, with seamless export into SaberRD. SaberRD adds an integrated design and simulation environment for mechatronic systems, with best-in-class analysis for power electronics validation.
Saber is a general purpose simulation program from Synopsys, Inc. It was originally developed by Analogy, Inc.;[1] which was bought by Avanti Corporation in 2000;[2] that was then bought by Synopsys, Inc.[3]
Saber began as a single-kernel analog simulation technology which brought VHDL-AMS, Verilog-AMS, SPICE, and the Saber-MAST language into a single environment. Saber was coupled to digital simulators via the Calaveras algorithm. [4][5]
Can anyone let me know How can I get SABER simulation models for TI products? Normally manufacturers provide both SPICE and SABER models....but I couldnt see any SABER models on TI Website. In case Manufacturers do not provide SABER Models one can convert SPICE models into SABER models provided SPICE models are not encrypted. As TI's SPICE models are encrypted I dont have this option either.
You will need the unencrypted PSpice model for this. For this we will need an NDA with your company. Please contact your local TI Representative for this. However note that the model was developed in PSpice and so there is no guarantee that it will work in Saber.
