Siemens has acquired COMSA Computer und Software, a Munich-based company which develops software for electrical systems design and wire harness engineering.

The company's LDorado suite is the leader in automotive harness design and engineering software in Germany, and it has a well-established product portfolio and 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.

“The acquisition of COMSA is part of Siemens’ continued investment in technology
for the automotive industry,” said Tony Hemmelgarn, president and CEO of Siemens
PLM Software.

“The combination of Siemens and COMSA solutions and specialist staff is unrivalled 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.”

Bishop and Associates estimate that in 2017 the worldwide revenue for the cable
assembly market was $155 billion with approximately 30% of the market from

According to Cowen Research (Oct.19, 2018), “The wiring harness today is the third highest cost component in a car (behind the engine and chassis). Harnesses are built one at a time and can comprise about 50 percent of the cost of labour for the entire car. The wiring harness is also the third heaviest component (behind the chassis and engine). Any technology that reduces this weight directly contributes to fuel economy.”

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’ 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
