Siemens agrees to buy Lauterbach to expand chip-testing tools
The purchase would combine Lauterbach’s debugging technology with Siemens’ chip simulation systems. Financial terms were not disclosed.
Siemens has agreed to purchase Lauterbach, a German developer of chip and software debugging tools, for its electronic design automation (EDA) business. Completion is expected during the first half of 2027, pending regulatory approval.
The company aims to connect Lauterbach’s technology with its existing hardware systems, which simulate chips before production. Siemens said this would enable customers to test chip designs and software together, potentially identifying errors and beginning software development before physical chips become available.
Lauterbach’s TRACE32 product range helps engineers observe a chip’s behavior while software operates and locate faults. More than 1,200 customers use its tools, primarily across the automotive, semiconductor and telecommunications industries.
Brothers Lothar and Stephan Lauterbach established the company in 1979. It employs about 170 people and is headquartered in Höhenkirchen, near Munich. Siemens developed its EDA operations largely through the purchase of Mentor Graphics in 2017.
Stephan Lauterbach, co-founder and chief technology officer, said the business would maintain its customer focus. He and Thomas Ullmann will join Siemens when the transaction closes. Siemens said it anticipates significant additional sales from the acquisition.
