Synopsys completes $35 billion acquisition of Ansys

On July 17, 2025, Synopsys officially completed its acquisition of Ansys, a deal worth around $35 billion that had been in the works for 18 months. This acquisition followed extensive negotiations and regulatory reviews across several major markets, including the United States, European Union, United Kingdom, and China. By merging their capabilities, Synopsys aims to strengthen its position in electronic design automation by integrating Ansys’ advanced multi-physics simulation technologies with its semiconductor intellectual property. Both companies had collaborated for many years prior to the acquisition, establishing a strong foundation for a combined entity. The goal is to provide deeper integration between design processes and simulations at every stage of product development, ranging from the transistor level to entire systems. This strategic decision responds to the increasing demand for simulation in the design of complex ecosystems, especially in industries like automotive, AI, and advanced telecommunications. The merger will allow for significant improvements in IP sharing and will facilitate a much closer alignment of their software and tools. Synopsys aims to enhance existing platforms and ensure product interoperability, pledging to support Ansys customers while also incorporating multi-physics features into its existing chip design and verification tools. Initial joint solutions are slated for release in the first half of 2026, focusing on advanced design challenges involving electrical, mechanical, and thermal intersections. As devices continue to grow more complex, traditional design handoffs are becoming insufficient. Synopsys sees this acquisition not only as a means to speed up time to market but also to empower engineers with a unified platform for simulating real-world conditions during the design process. This integration positions Synopsys and Ansys to address the next generation of intelligent systems that prioritize efficiency and safety across a wide range of industries including edge devices, electric vehicles, aerospace, and digital twins.
