Announcement of Sales Launch for Switching Power Supply Circuit Simulator 'SIMPLIS' and Analog/Mixed-Signal Circuit Simulator 'SIMetrix'

Cybernet Systems Co., Ltd. (Headquarters: Tokyo, Japan; President and CEO: Zenji Shiraishi, hereinafter 'Cybernet') announces that, as the exclusive national distributor in Japan, it will begin sales and technical support for 'SIMetrix/SIMPLIS' (pronounced Simetrix/Simplis), circuit simulation products developed and sold by SIMPLIS Technologies, Inc. (Headquarters: Oregon, USA; hereinafter 'SIMPLIS'), effective August 1, 2026.

Increasing Importance of Circuit Design Amid Rising Demand for High Integration and Performance

Driven by the growing demand for AI and data centers and the miniaturization of IoT devices, the field of electronic circuit design, particularly in power electronics, faces increasing demands not only for high integration, high speed, and low power consumption but also for high efficiency.

In particular, designing power electronics circuits such as switching power supplies and complex analog/mixed-signal circuits (※1) has become more challenging. The increasing complexity of circuit configurations and diverse operating conditions have led to a growing verification burden during the design phase. Prolonged analysis times, ensuring convergence and stability, improving analysis accuracy, and challenges related to tool compatibility and model conversion have made it difficult to conduct sufficient verification before prototyping.

To address these challenges, the importance of efficient design and verification environments that can shorten development cycles while maintaining design quality is increasing.

'SIMetrix/SIMPLIS': Pioneering the Future of Circuit Design with Speed, Accuracy, and Efficiency

'SIMetrix/SIMPLIS' is an integrated design environment combining 'SIMetrix,' equipped with a SPICE-based (※2) simulation engine for analog/mixed-signal circuit design, and 'SIMPLIS,' featuring a simulation engine optimized for switching power supply analysis. It provides practical solutions to various challenges faced in power circuit design.

Analog/Mixed-Signal Circuit Simulator 'SIMetrix'

SIMetrix is a circuit simulation software that enables the reproduction of electronic circuit behavior on a computer, allowing performance and operation to be verified during the design phase. Its high-performance analysis engine enables fast and stable simulations. Hundreds of sample circuits applicable to various designs are provided, enabling efficient design and verification even for large-scale and complex electronic circuits.

Furthermore, SIMetrix offers extensive compatibility with various SPICE models, supporting the construction of efficient development environments that leverage accumulated design data, thereby contributing to the efficiency and quality improvement of electronic circuit design.

Switching Power Supply Circuit Simulator 'SIMPLIS'

SIMPLIS is a circuit simulation software that enables the reproduction of switching power supplies and power electronics circuits on a computer, allowing performance and stability to be verified during the design phase. It is a tool designed to provide a simulation environment specialized in high-speed, high-precision analysis of switching power supplies and power electronics circuits.

Through its proprietary analysis algorithm, SIMPLIS achieves simulation speeds approximately 10 to 50 times faster than conventional SPICE-based circuit simulators, enabling stable results to be obtained quickly even for complex power circuits such as DC-DC converters. Additionally, its ability to quickly identify stable operating states allows for efficient evaluation of power circuit stability.

Moreover, for common component models such as MOSFETs (※3), BJTs (※4), and diodes, models usable in SIMPLIS can be created based on evaluation results from SIMetrix. This enables existing SPICE models to be utilized in SIMPLIS simulations.
