The operation will allow combining Lauterbach's debugging technologies with Siemens' hardware-assisted verification solutions, with the aim of providing a unified view of hardware and software behavior during semiconductor development.
Lauterbach develops modular and scalable tools for embedded software debugging and real-time trace analysis, used in microprocessors and embedded CPU cores. Their integration will allow Siemens to expand its electronic design automation (EDA) portfolio by combining hardware verification and software debugging processes that are traditionally performed separately. The combined solution will enable the analysis of interactions between these two environments during the development of application-specific integrated circuits (ASICs) and systems-on-a-chip.
One of the main objectives is to enable engineers to develop and verify embedded software before the physical chip is available, detecting potential problems in the early stages. This approach, known as shift-left, allows testing and validation activities to be brought forward, reducing the costs and time associated with debugging.
Applications in artificial intelligence and automotive
The increasing complexity of semiconductors and embedded software is driving greater integration between hardware and software development processes. This trend is particularly relevant in sectors such as artificial intelligence, software-defined vehicles (SDVs), the Internet of Things (IoT), and multi-core architectures. It is also gaining importance in applications requiring high levels of cybersecurity and functional security. The combination of Siemens and Lauterbach technologies will target high-performance computing applications, data centers, storage, automotive, communications, aerospace, and defense.
Lauterbach is headquartered near Munich and was founded by brothers Lothar and Stephan Lauterbach, who began developing tools for microprocessors in 1979. The company currently has approximately 170 employees and more than 1,200 customers worldwide, including manufacturers and technology companies in the automotive, semiconductor, and telecommunications sectors. It projected revenues of nearly €60 million in 2025.
Siemens expects to complete the transaction during the first half of 2027, provided that customary closing conditions are met and the necessary regulatory approvals are obtained.
Following the completion of the acquisition, Stephan Lauterbach and Thomas Ullmann will continue to develop their activities within Siemens.
