Keysight Technologies completed the acquisition of VPIphotonics on June 9, 2026, adding system-level simulation to its photonic design automation portfolio. The acquisition enables optical and electrical engineers to advance designs from component to complete link within a single environment, addressing the growing demand for silicon photonics and co-packaged optics in data center and AI infrastructure markets.

Integrated Design Workflow

The expanded portfolio now reaches from device physics to full system behavior. RSoft handles device-level simulation for waveguides, gratings, modulators, and laser sources. Photonic Designer delivers comprehensive circuit-level design and verification for photonic integrated circuits. The addition of VPIphotonics Design Suite strengthens circuit-level capabilities and extends the portfolio to the system level.

Key Portfolio Components

Enhanced Simulation Capabilities

One example of the integrated workflow is VPI Optical Link in Keysight ADS, which enables simulation of the full transceiver path in a single analysis, from electrical to optical and back to electrical (E-O-E). Engineers can predict how the whole link will perform, including bit error rate, without moving a design between separate electrical and optical tools. Because the workflow connects to Keysight's high-speed digital tools and test instruments, simulation aligns with bench measurements, allowing issues to surface earlier and reducing the need for prototype iterations.

Management Commentary

Dr. André Richter, General Manager, VPIphotonics, said: "We have been supporting our customers with value-adding photonic design tools for high-demand applications for decades. Joining Keysight means we can engineer powerful, more complete workflow solutions to serve our customers better."

Nilesh Kamdar, General Manager, Keysight EDA, said: "Photonics design complexity continues to increase for our customers, especially for those working at speeds greater than 1 THz. Having a complete suite of tools that address these challenges from device to system is crucial. We're excited to welcome the VPIphotonics team to Keysight and help us address the critical design challenges our joint customers face."

Terms of the transaction have not been disclosed.

Keysight Technologies has joined the Siemens Digital Industries Software Solution Partner Program as a Software and Technology Partner. The collaboration enables customers to access Keysight Eggplant Test, an AI-driven test automation solution, to validate their digital engineering and product lifecycle management (PLM) environments. This integration addresses the growing pressure on manufacturers to shorten development cycles while managing increasingly complex software-driven products.

Siemens Digital Industries Software develops solutions for engineering, manufacturing, and product lifecycle management. Through this partnership, customers using the Teamcenter software can deploy Keysight Eggplant Test to validate enterprise applications and engineering workflows before they reach production. The solution is designed to address operational challenges where manual processes are often too slow and inconsistent to handle testing at scale.

Strategic Benefits

The partnership focuses on enhancing system performance and reliability throughout the product lifecycle. As PLM environments grow in complexity, organizations require reliable methods to validate software before deployment. By integrating AI-driven testing, engineers can mitigate risks associated with undetected issues during upgrades or system integrations.

Executive Insight

Gareth Smith, Software Quality Engineering General Manager at Keysight, emphasized the importance of the collaboration. "As PLM environments grow in complexity, organizations need a reliable, AI-driven way to validate software before it reaches production," Smith said. "By joining the Siemens Digital Industries Software Solution Partner Program, engineers can use Keysight Eggplant Test to reduce the risk of undetected issues when upgrades or integrations are released, maintaining system performance and reliability at every stage of the product lifecycle."
