SabreEXP virtual prototyping for power systems

Synopsys has launched a virtual prototyping system to accelerate power electronics system design from concept to validation for power components to large complex systems.

SaberEXP  provides fast simulation convergence for early power component design, such as power converters and motor drives. It also provides a seamless export flow into high fidelity large system design using the SaberRD tool.

This has been driven by the increasing electrification of automotive, aerospace and industrial systems. These systems require increasingly complex and efficient power electronics subsystems to ensure maximum power delivery and use. These changes have increased the development cost and reduced the productivity of developers.

Better methodology and tools addressing concept design studies, electrical component selection, scalability to large systems including validation in the context of software, and dependency on expensive physical testbenches are required.

The use of a scalable virtual prototyping solution from concept to validation of power electronics systems enables design teams to start development early and validate their design prior to physical implementation, leading to better products and lower development costs.

“As power electronics continue to advance in complexity, it’s essential to validate designs early, well before physical implementation,” said Peter Wilson, Professor of Electronics and Systems Engineering at University of Bath. “Fast simulation is absolutely essential to performing validation early and ensuring design fidelity. Synopsys SaberEXP provides a fast and efficient way to carry out rapid evaluations of design concepts before carrying out system level and complex multiple-domain analysis using SaberRD.”

SaberEXP’s high abstraction models and piecewise linear (PWL) solver provide high accuracy and convergence for power converters and motor drives for fast time to result. The tool includes a general-purpose high-abstraction model library with a high-speed mixed mode solver to verify the stability of switched mode power supplies. Parametric and statistical design capabilities accelerate the optimization and verification of design robustness and there is minimal simulation tuning, making the tool more robust than SPICE-based tools says Synopsys.

SaberEXP designs can be seamlessly imported into SaberRD allowing high-fidelity simulation, handling of large systems and leveraging a rich feature set for robust design.

“Automotive, aerospace and industrial embedded systems integrate increasingly complex and feature-rich power electronics, digital hardware and software,” said Tom De Schutter, vice president of Engineering at Synopsys. “The introduction of SaberEXP enables our customers to deploy a faster, more productive and standardized solution for power electronics from concept to validation and leverage its integration with our broader virtual prototyping products for embedded system verification and validation.”

SaberEXP is available now.
