Synopsys today announced that it has received all necessary approvals to proceed with its previously announced plan to divest its Optical Solutions Group and PowerArtist businesses to Keysight Technologies, Inc.

Regulators determined these divestitures were necessary for Synopsys' acquisition of Ansys, which successfully closed on July 17, 2025. Synopsys expects to complete these divestitures on or about October 17, 2025.

The transaction has no material impact on Synopsys' financials, and terms of the agreement were not disclosed. Synopsys remains committed to providing a seamless transition for its employees, customers, and partners.

Synopsys sells Optical Solutions Group

Last September, Synopsys announced it had entered into a definitive agreement to sell its Optical Solutions Group (OSG) to Keysight Technologies, a leading provider of design, simulation, and test solutions. The sale of OSG was considered a necessary step to obtain regulatory approval and successfully complete Synopsys' proposed acquisition of Ansys.

"We are proud of Synopsys' Optical Solutions Group, which develops leading optical design tools and employs an expert team of optical engineers and scientists," said Ravi Subramanian, general manager of Synopsys' System Design Group. "Keysight will be an excellent steward of this team for the future, and our global customers will benefit from continued strong competition in the development and delivery of optical design solutions."

OSG

OSG provides design tools and services that model all aspects of light propagation to enable highly accurate optical product simulation and visualization. These include CODE V for imaging system design, LightTools illumination design software, LucidShape for automotive lighting design, RSoft photonic device tools, and the recently released ImSym, a groundbreaking virtual prototyping platform for imaging systems. These tools provide intelligent, easy-to-use solutions, backed by an expert team of optical engineers, helping customers bring superior optical products to market faster.

"Given the growing complexity of electronic design, Keysight is excited to expand its software simulation portfolio with the acquisition of Synopsys' Optical Solutions Group," said Niels Faché, vice president and general manager of Design Engineering Software at Keysight. "This acquisition will enable us to support high-performance system use cases beyond electronics, including optics and photonics. We look forward to welcoming the group's employees to Keysight after the transaction closes and collaborating with them to address our customers' critical design challenges in predicting product performance through multiphysics simulation."

The transaction has no material impact on Synopsys' financials, and terms of the agreement were not disclosed. Synopsys is committed to providing a seamless transition for the OSG team, customers, and partners. Until the transaction closes, OSG will continue to operate as part of Synopsys, focusing on execution, customer service, and continuous innovation.

Synopsys sells Ansys PowerArtist

Earlier this year, Synopsys and Ansys announced that Ansys had entered into a definitive agreement to sell its PowerArtist business to Keysight Technologies, a global leader in semiconductor, electronics, and high-performance system design and simulation software. Ansys and Synopsys agreed that the sale of the PowerArtist business was necessary to obtain regulatory approval.

PowerArtist is a comprehensive RTL power design platform used by semiconductor companies for early power analysis, performance profiling, and reduction. Compared to traditional gate-level approaches, PowerArtist can rapidly process millions of design instances, enabling power-related design decisions to be made earlier in the design process.

"We are proud of the role PowerArtist has played in driving low-power innovation in semiconductor design applications," said John Lee, vice president and general manager of Ansys' Electronic Semiconductor and Optical Business Unit. "As part of the Keysight portfolio, PowerArtist will continue to thrive as a leading, independent RTL power product that is not tied to a specific vendor's design implementation flow."

Keysight is a major supplier to semiconductor and electronics companies worldwide. Its planned acquisition of the PowerArtist business further strengthens its position in high-performance system design and simulation software. "Our acquisition of the RTL Power Design solution from Ansys further expands our portfolio of design engineering software solutions," said Niels Faché, vice president and general manager of Design Engineering Software at Keysight Technologies. "We look forward to strengthening our offering in the digital systems space and warmly welcome the PowerArtist team to Keysight."

The sale of PowerArtist will have no material impact on Ansys' financial performance, and terms of the agreement were not disclosed. Both parties are committed to providing a seamless transition for the Ansys PowerArtist team, customers, and partners. During the transition period leading up to the closing of the transaction, Ansys will continue to offer PowerArtist as part of its product line and is committed to providing customers with consistent, high-quality service.
