# Siemens plans acquisition of Lauterbach to enhance chip and software verification

Siemens announced on November 10, 2026, an agreement to acquire Lauterbach, a German specialist in debugging and tracing tools for embedded software. The group aims to strengthen its electronic design offering and enable developers to test chips and their software together before the fabrication of components.

The amount of the transaction has not been disclosed. Lauterbach is set to join Siemens' electronic design automation division, known as EDA. This branch, which provides design and verification tools for chips, has notably expanded with the acquisition of Mentor Graphics in 2017.

Founded in 1979 by brothers Lothar and Stephan Lauterbach, the company is based in Höhenkirchen, near Munich. It employs approximately 170 people and generated about 60 million euros in revenue in 2025. It has over 1,200 clients, particularly in the automotive, semiconductor, and telecommunications sectors.

Its TRACE32 range allows engineers to observe the operation of chips during software execution and to search for errors. Lauterbach also has offices in the United Kingdom, Italy, France, Tunisia, the United States, Japan, and China.

Siemens plans to integrate these technologies with its hardware-assisted verification solutions. The goal is to combine previously separate workflows to give teams a common view of the behavior of circuits and embedded software. Developers could thus identify errors related to their interactions earlier.

This approach particularly concerns application-specific integrated circuits, or ASICs, and system-on-chip solutions, or SoCs. Siemens aims to reduce development and time-to-market delays. The group emphasizes that artificial intelligence, software-defined vehicles, the Internet of Things, multicore architectures, cybersecurity, and functional safety heighten the convergence between hardware and software. It also anticipates significant revenue synergies, as both companies already share numerous clients, according to its statement.

Finalization is expected in the first half of 2027, subject to customary conditions and necessary regulatory approvals. Stephan Lauterbach and Thomas Ullmann will continue their activities within Siemens after the deal closes.
