Mazda drives engineering creativity using Siemens’ model-based generative engineering tools 2019-08-16

The Capital electrical design software suite can help Mazda optimize vehicle development by creating a seamless development environment, helping manage the complex designs required for the future of mobility.

Mazda Motor has adopted the Capital electrical design software suite from Mentor to help increase innovation in the design of automotive electrical systems.

Mazda is using Capital for model-based generative design for the electrical and electronic systems of the entire vehicle platform. The Capital automated generative design flow helps Mazda automotive design teams manage design complexity and changes across the entire vehicle platform, reducing errors and costs.

The development of safe and efficient electrical designs has become a critical task as the automotive industry moves towards large-scale system developments such as electrified powertrains and autonomous driving. These designs are often based on entirely new architectures and have become so complex that advanced software tools are needed to enable development efforts.

Capital tools provide real-time feedback against target metrics such as cost, weight and network bandwidth consumption. This allows engineers to explore alternative design approaches, which is important for large-scale system developments represented by electric and autonomous vehicles. Capital software also provides Mazda with simulation and verification functionalities.

At Mazda, from system design, harness design and verification down to manufacturing and service documentation, outputs of each process have been generated in its natural language, requiring designers to translate between processes and fill in the missing pieces using their talents and skills.

“To remove ambiguity while maintaining the diversity of expressions that are characteristics of these natural languages, we applied formal methods to eliminate the loss in information transfer and set a goal to build a development environment that is consistent and connected all the way through the manufacturing phase,” said Kazuichi Fujisaka, technical leader at Mazda Motor. “Furthermore, we also aim to shift to a development methodology that allows us to optimise the vehicle as a whole, with all possible variations being considered in the early development stage.”

To make this happen, Fujisaka said Mazda needed a development environment to visualise the entire vehicle circuitry and standardise language, tools and processes without compromise, creating standard models across the company.

“Mentor’s Capital technologies provide this environment and make Mazda’s electric development much more efficient,” said Fujisaka.

In addition to the Siemens subsidiary Mentor’s Capital electrical design software suite, Mazda also uses Siemens’ NX software and Teamcenter portfolio for enterprise collaboration.

“One who keeps challenging what seems impossible leads innovation, a fact Mazda clearly understands, as evidenced by its long history of innovation,” said Martin O’Brien, senior vice president at Siemens. “As a long-standing Capital customer, Mazda has proven to be a fast adopter of new capabilities, such as platform-level architecture optimisation spanning the electrical, electronic, networking and embedded software disciplines. As a growing number of Japanese automotive OEMs adopt Capital, Mazda has established its reputation as a forward-thinking early adopter, with a long track record of leveraging our sophisticated technologies from their customer-first point of view.”

In addition to the Capital Electrical Design Software suite, Mazda also uses Siemens’ NX™ software and Teamcenter® portfolio for enterprise collaboration. To learn more about the Capital solution, visit: https://www.mentor.com/products/electrical-design-software/.
