In January 2024, the partnership between Synopsys and Ansys was first revealed and officially concluded on July 17, 2025. This merger brings together Synopsys’ expertise in electronic design automation (EDA) and semiconductor IP with Ansys’ strengths in multi-physics simulation and analysis. Regulatory approvals have been secured in the U.S., EU, UK, and China. The deal unites two complementary product lines and reflects a growing necessity for tighter integration between electronics and physics throughout the entire product development cycle — from the transistor level to full system design.

Simulation Plays a Critical Role in System Design

Though Synopsys and Ansys have collaborated for years, this merger allows for more extensive IP sharing and eventual unification of their software and tool ecosystems. By embedding Ansys’ multi-physics simulation engines into Synopsys’ EDA tools, the company can facilitate simultaneous, simulation-driven co-design across silicon, PCBs, packaging, and complete system architecture — enhancing results and accelerating time to market.

This level of integration is especially vital in fields such as chiplet-based design, AI accelerators, 5G infrastructure, and automotive platforms, where the interplay between hardware, software, and environmental factors affects a product’s success and performance. With increased use of digital simulations throughout the design process, companies can now optimize performance, power efficiency, size, and reliability long before a chip is finalized or a system prototype is built.

Expanded Scale and Market Reach

The newly formed entity is positioned to serve a much broader market, estimated at $31 billion, covering core EDA, IP, and multi-physics simulation. Financial analysts have responded positively, highlighting potential long-term revenue synergies and improved operational efficiency. Several investment firms have raised their outlook for Synopsys, recognizing its unique ability to offer a more comprehensive suite of design and simulation tools. This move also strengthens Synopsys' position against rivals like Cadence and Siemens EDA.

Integration Plan and Customer Interaction

Synopsys has laid out a structured integration plan aimed at maintaining customer satisfaction while delivering enhanced value. The company has committed to supporting Ansys’ current customer base and ensuring continued interoperability between both platforms. Initial integration efforts are focused on incorporating multi-physics simulation into Synopsys’ chip design and verification tools, as well as enabling co-simulation for advanced 2.5D and 3D multi-die systems.

In a conversation with Shankar Krishnamoorthy, Chief Product Development Officer at Synopsys, I learned that joint product offerings are expected in the first half of 2026. These will target key areas where electrical, mechanical, and thermal challenges converge — such as heterogeneous integration, power-aware verification, and real-time system-level analysis for critical applications. In the near term, the acquisition enables deeper IP collaboration, allowing both the company and its clients to reimagine design workflows for improved results and faster time to market.

While the strategic fit between the two companies is clear, successful execution will be crucial. Merging two engineering-focused cultures and complex product lines is always a challenge. However, Synopsys’ track record of integrating acquisitions and its long-standing collaboration with Ansys suggest a smooth transition is likely.

A Comprehensive Design and Simulation Platform for the AI Age

As devices grow more complex and development timelines shrink, traditional handoffs between engineering disciplines are no longer sufficient. With Ansys’ technology now part of its portfolio, Synopsys is better equipped to offer simulation-driven design workflows that span from the transistor level to full system deployment.

Ultimately, this acquisition is about enabling the next wave of intelligent systems — not just higher-performance chips, but smarter, safer, and more efficient products across industries. From edge computing and electric vehicles to aerospace and digital twin technologies, the Synopsys-Ansys merger delivers a unified platform that empowers engineers to simulate real-world conditions as part of the design process — a key factor in speeding up time to market and achieving optimal outcomes, especially when engineering talent is in short supply.
