SaberRD Experiment Analyzer
The new SaberRD Experiment Analyzer lets you quickly set-up and re-use experiments, simulate, and analyze simulation results. The Experiment Analyzer supports traditional Saber analysis or at-a-glance examination of experiment pass/fail criteria. Results from experiments can be exported directly to excel or other standard file formats for additional processing or reporting.

Saber Functional Safety Add-on
Saber Functional Safety Add-on helps you meet functional safety requirements, like ISO26262 for automotive applications. In addition to simple hardware faults including: open, short, ground, and stuck-at faults; Saber Functional Safety Add-on also supports sophisticated fault modes including parameterized faults, concurrent faults, and timed faults. Saber's fault modeling and simulation technology can be used in the functional safety life cycle to validate FMEA/FTA analysis and to determine diagnostic coverage of safety mechanisms in E/E systems, or simply improve internal reliability processes. The Saber Functional Safety Add-on can be used with the Experiment Analyzer and Saber Runtime to achieve maximum productivity and throughput, respectively.


Improved SaberHDL Convergence
Refinements to SaberHDL, the Saber simulator that supports both MAST and VHDL-AMS, improves convergence for designs with complicated non-linearities typically found in pulse-width modulators, data converters, and analog feedback systems. Moreover, debugging designs for non-convergence is made easier with a new link between error messages and problem elements in SaberRD schematics.


Interface to Synopsys Virtualizer
A new interface to Synopsys Virtualizer combines Saber's accurate power system and physical plant models with precision Virtualizer TLM models for digital controllers. The interface supports nominal design and iterative simulation for robust design and functional safety applications.


Interface to JMAG-RT
A new Saber interface to JMAG-RT supports plant models for rotating machines for MiL and SiL applications. This new interface improves early-verification and prototyping flows for mechatronic systems by combining FEA-accurate electric machine models with high-fidelity Saber motor-drive models and control software modeled natively in Saber or brought in from other tools.


IGBT Model Enhancements
Enhancements to native Saber IGBT models and modeling tools improve simulation accuracy of high-power electronic systems. What's more, the Synopsys TCAD-generated IGBT model has been refined to predict turn-on loss and overshoot to within 10% of baseline TCAD simulations.


Other Features in 2013.12
Enhanced PSpice Model Support: Coverage of non-standard PSpice semantics has grown to include PSpice tolerance functions, models with .model declarations, and the R parameter in PWL sources. A new filter removes extraneous overhead from the target Pspice models to simplify the automatically generated Saber models and make them more readable.

User-defined SaberRD Toolbars: User-configurable toolbars in SaberRD enable quick and easy access to commonly used option, configuration, analysis, and simulation settings. Custom toolbars can also be used to standardize enterprise-wide Saber roll-out for common look and feel and easier support.
