Capital X” for DXing increasingly complex electrical and electronic system designs

With the advancement of EVs and automated driving technology, the design of electrical and electronic systems for automobiles is becoming more complex than ever before.
For example, the number of wires in a conventional compact car was about 1,200 to 1,500, but has increased to about 1,800 with the advent of EV and hybrid vehicles and the introduction of driver assistance systems and collision prevention features.
For large sedans, the number of wires has increased from about 2,500 to more than 3,000, and the man-hours required for design and verification work have increased significantly accordingly.

In addition, the management of vehicle specification configurations is becoming more diversified, with as many as 1 million combinations of different domestic and overseas specifications, driver assistance systems, anti-collision features, and so on.
There are limits to conventional manual and Excel-based design management, and issues such as the risk of design errors and lack of coordination between rework departments have become apparent.

What we would like to focus on is an initiative to connect the entire process from upstream development to manufacturing and after-sales service through a consistent digital thread.
For example, Mazda was facing a problem in the coordination of circuit design and harness design in the design of electrical and electronic systems, but through the establishment of digital threads, the company was able to achieve a consistent flow of data.

By combining this with vehicle configuration information, Mazda was able to dramatically reduce man-hours by replacing manual harness wiring with rule-based automatic wiring.
These efforts are now being deployed outside the automotive industry, including by aircraft manufacturer Airbus, as well as in agricultural machinery and space probes.

This report describes the approach for streamlining the increasingly complex design of electrical and electronic systems through DXing.
The specific benefits of the solutions that support these efforts are also introduced, so please request more information.
