Bringing silicon and simulation under one roof, Synopsys and Ansys gear up to close a $35 billion mega-merger this week, which could reshape the future of AI design.
US-based semiconductor design firm Synopsys has received clearance from all required regulatory bodies to complete its planned takeover of Ansys, another engineering firm in the US. The deal, announced in January 2024, is valued at approximately $35 billion. It involves a mix of cash and stock and will see Synopsys acquire 100% of Ansys.
The companies expect to finalise the transaction around Thursday, 17 July 2025, along with pending completion of final routine conditions.
The acquisition will combine Synopsys’ expertise in silicon design and semiconductor IP with Ansys’ strength in engineering simulation software. The goal is to create a comprehensive solutions provider spanning chip design to full system-level simulation.
Synopsys has said the integration will help customers accelerate innovation, particularly in artificial intelligence (AI)-driven technologies.
Regulators in the US, UK, EU, and most recently China have reviewed and approved the transaction. China’s State Administration for Market Regulation gave conditional approval earlier this week, requiring that Synopsys maintain existing terms with Chinese clients and ensure fair access to its software tools. This was the final hurdle.
Earlier concerns centred on national security and competition in the electronic design automation (EDA) and simulation sectors, particularly due to rising US-China tech tensions.
The deal carries strategic weight, with China accounting for a notable share of both companies’ revenues. Analysts see this merger as reinforcing Synopsys’ competitive position in the high-growth AI, automotive, and electronics markets.
Once completed, the transaction is expected to strengthen Synopsys’ product portfolio and global footprint. The company mentioned that this also marks one of the largest software acquisitions in recent years.
