Synopsys claims virtual prototyping tool has fastest convergence

Virtual prototyping enables design teams to start development early and validate their designs prior to physical implementation. This leads to better products and lower development costs, says Synopsys. It has introduced SaberEXP, to deliver fast convergence for early power component design, and seamless exports the design to high fidelity system validation.

The electrification of automotive, aerospace and industrial systems has increased the power electronics component and system complexity.

According to McKinsey & Company, automotive is fuelling the power electronics market expansion with an expected 15 per cent compound annual growth rate (CAGR) between 2020 and 2030. Such 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.

SaberEXP delivers fast simulation convergence and higher productivity for early power component design (e.g. power converters and motor drives) while also providing a seamless export flow into high fidelity large system design using Synopsys’ power electronics tool, SaberRD.

“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,” he added.

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. It includes a comprehensive, general purpose high abstraction model library and high-speed mixed mode solver to verify the stability of switched mode power supplies. SaberEXP also has parametric and statistical design capabilities to accelerate the optimisation and verification of a design’s robustness.

It has also be designed to be easier to use, with minimal simulation tuning, and is more robust than SPICE-based tools, says Synopsys.

SaberEXP designs can be seamlessly imported into SaberRD allowing high fidelity simulation and the handling of large systems.

SaberEXP and SaberRD are part of Synopsys virtual prototyping products including Silver and Virtualizer.

Synopsys SaberEXP is available now.
