Siemens announced today that it will acquire COMSA Computer und Software. The German company develops software for the design of electrical systems and cabling in cars. The LDorado software is the market leader in this field in Germany and will soon be part of Siemens’ automotive portfolio.

COMSA’s team will, together with the technology, join the Mentor division of Siemens PLM Software. It then adds important cable harness engineering and design data analysis capabilities to Siemens’ portfolio. The amount of money involved in the takeover is not known. The transaction was completed on 3 December 2018.

Valuable investment

According to Tony Hemmelgarn, president and CEO of Siemens PLM Software, the acquisition of COMSA is part of the company’s ongoing investment in technology for the automotive industry. The combination of Siemens and COMSA solutions and specialists creates a unique position within the industry. Together, the companies want to innovate and meet the demand for electric and self-propelled vehicles.

It is a valuable market in which Siemens PLM Software invests. Analysts such as Bishop & Associates estimate that last year’s global wiring engineering sales amounted to $155 billion. Thirty percent of this is accounted for by automotive. The cabling is the third most expensive component of a car today. It is also the third heaviest part. Any technology that reduces this weight makes a car more economical, according to Siemens.


Siemens PLM Software announces that it intends to expand the supply of new technology for the wiring harness industry worldwide through the acquisition. Earlier it took over Mentor Graphics, which helps with the design of electrical systems, to make a difference. The acquisition of COMSA helps and adds key analytical technology and skills to the company’s portfolio.

Josef Biermeier, CEO of COMSA, emphasizes in his statement that the combination of COMSA and Siemens is a win-win for both our companies, for our customers and the entire automotive industry.
