Siemens to buy German debug specialist Lauterbach in chip-design push
What's the deal? Siemens has agreed to acquire LauterbachDealroom has a profile for this one. Try Dealroom →, a German maker of debug and trace tools for embedded systems. Terms were not disclosed, and the deal is expected to close in the first half of 2027, subject to approvals.
What each side brings: Lauterbach, founded in 1979, is a global leader in debug and trace, known for its TRACE32 tools that help developers analyse embedded software across the system-on-chip (SoC) lifecycle. Siemens adds it to a growing electronic-design-automation (EDA) portfolio built around hardware-assisted chip verification.
What's the endgame? The combination aims to give customers one verification flow from pre-silicon design to final product. "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.
Why now? Modern semiconductors are growing more complex, driven by AI, software-defined vehicles, and multi-core architectures. That is forcing tighter integration between hardware and software development.
Co-founder and chief technology officer Stephan Lauterbach said the "increasing convergence of hardware and software development is fundamentally changing the industry." He and Thomas Ullmann will stay on after closing.
The signal: The deal extends a Siemens buying streak in chip tools. In July 2026 it agreed to buy Defacto TechnologiesDealroom has a profile for this one. Try Dealroom → to automate SoC design, alongside a deal for Precision Innovations'Dealroom has a profile for this one. Try Dealroom → chip-planning tools. Lauterbach adds a complementary piece—linking chip verification with the software that runs on it—as Siemens pushes toward an end-to-end development workflow rather than a standalone market expansion.
