Siemens Acquires COMSA to Further Extend Lead in Automotive Electrical Systems Design

Siemens announced the acquisition of COMSA, a Munich-based company which develops software for electrical systems design and wire harness engineering.

Its LDorado suite is the one of the leader in automotive harness design and engineering software in Germany, reflecting deep local expertise and market presence with a well-established product portfolio and a strong emphasis on standards. The COMSA team and technology will join the Mentor business, part of Siemens PLM Software, where it will add key harness engineering and design data analytics capabilities to the Siemens product range.

Siemens COMSA
Modern automotive electrical systems are impossible to design and manufacture without sophisticated technology. The combination of Siemens’ Capital software and COMSA’s LDorado technology will provide new levels of electrical systems and harness engineering to the entire automotive industry.

“The acquisition of COMSA is part of Siemens’ continued investment in technology for the automotive industry,” noted Tony Hemmelgarn, president and CEO of Siemens PLM Software. “The combination of Siemens and COMSA solutions and specialist staff is unrivaled in the industry. Together, we will take electrical systems and harness engineering to the new levels needed to meet the demands of electric and autonomous vehicle development, and provide deeply integrated technical capabilities that will benefit COMSA and Siemens customers worldwide.”

Through this acquisition, Siemens plans to extend worldwide the delivery of new technology offerings that address disruption in the automotive harness industry caused by megatrends such as autonomous driving and electric vehicles.


Siemens Comsa LDorado
COMSA’s LDorado software strengthens Siemens’ global automotive presence with the addition of key capabilities in wire harness engineering and design data analytics.

Siemens’ Capital software, part of the portfolio of recently acquired Mentor Graphics, extends from electrical/electronic architecture development through electrical systems design and service into wire harness design and manufacture. The addition of COMSA adds key harness engineering and design data analytics technologies, with strong support for new data standards emerging especially in Europe.

“With Siemens’ acquisition of COMSA, we will be able to participate and contribute to this growing market in ways and locations that we could not have reached alone. The strength of COMSA’s LDorado software in wire harness engineering and analytics is a perfect complement to the Capital portfolio developed by Mentor, and we are excited to be a part of the forthcoming journey together,” commented Josef Biermeier, CEO of COMSA. ‘‘This combination is a win-win for both our companies, for our customers and the entire automotive industry.”

“We have long admired the COMSA team and their products, and through this acquisition, we are bringing together the complementary skills of two of the strongest players in the industry for the benefit of our customers,” said Martin O’Brien, senior vice president, Integrated Electrical Systems at Mentor, a Siemens business. “The combination of Capital and LDorado technology with Siemens expertise in adjacent design domains and factory automation will enable us to better assist our customers in transforming their operations’ competitiveness and increase profitability.”

The transaction closed on Dec 3, 2018. The terms of the transaction were not disclosed.
