HOEHENKIRCHEN, Germany, Nov 10, 2026 — Lauterbach announced that it has agreed to be acquired by Siemens. This marks a new era of “Enabling Embedded Innovations”, with customer value created from early chip design to system verification.
Lauterbach, a global leader in debug and trace solutions for embedded systems, agreed to be acquired by Siemens. This acquisition marks a new era in a success story that began in 1979. For more than four decades, Lauterbach has set the industry standard with its TRACE32 debug and trace tools, which help developers around the world debug and analyze embedded software across the entire SoC (system-on-chip) lifecycle. Its customers range from small companies to the world’s largest technology leaders. Following Closing and as part of Siemens, Lauterbach will take its claim “Enabling Embedded Innovations” to the next level, creating distinctive value for customers from early chip design to final system verification.
“The increasing convergence of hardware and software development is fundamentally changing the industry and our customers’ requirements,” said Stephan Lauterbach, CTO and co-founder of Lauterbach. “By combining our debug and trace technology with Siemens’ hardware-assisted verification and digital twin capabilities, we are creating a comprehensive solution that provides developers with a unified view of the hardware and software behavior of increasingly complex ASIC and SoC devices in AI, high-performance computing, automotive, communications and A&D applications.
“With Lauterbach, we are further extending our industry-leading EDA portfolio for semiconductor design by bringing together our premier hardware-assisted verification portfolio with its industry-leading software debugging technologies. As semiconductors represent a core vertical for our technology strategy, this enables customers to test and optimize their products even before the actual chip is produced – significantly reducing development time,” said Cedrik Neike, Member of the Managing Board of Siemens AG and President Digital Industries. “Lauterbach is a remarkable success story, written in Germany for the global semiconductor industry. We will build on the impressive legacy that founders Lothar and Stephan Lauterbach and their team have achieved over the past decades and are very pleased to welcome the Lauterbach group to Siemens. We are also delighted that Stephan Lauterbach and Thomas Ullmann will continue their work as part of Siemens following the closing of the transaction.”
The growing complexity of modern semiconductors and embedded software, driven by trends such as artificial intelligence, software-defined vehicles, the Internet of Things (IoT), multi-core architectures, cybersecurity, and functional safety, makes increasingly close integration between hardware and software development essential.
Together, Lauterbach and Siemens will help semiconductor and systems companies alike, to design for debug from the very first concept. With TRACE32® joining forces with Siemens’ hardware-assisted verification technology, customers gain one consistent functional verification flow from pre-silicon to the final product, including a path toward certifiable virtual validation for safety-critical applications.
Lauterbach and Siemens solutions are already trusted by numerous mutual customers. Siemens’ global presence will help bring Lauterbach’s solutions to an even broader customer base and new markets worldwide. Lauterbach’s gold-standard, high-quality products, broad architectural support, and renowned technical expertise along with customer-centric support will remain unchanged and at the same time further strengthen Siemens’ position and expand its reach in the chip design and verification market.
The transaction is expected to close in the first half of 2027, subject to customary closing conditions and required regulatory approvals.
The financial terms of the transaction will not be disclosed.
