The increasing complexity of software due to the acceleration of SDV (Software Defined Vehicle)

The role required of in-vehicle ECUs is changing dramatically due to the proliferation of xEVs, advancements in autonomous driving technology, and the acceleration of SDV (Software-Defined Vehicle) development. In particular, the rapid progress of SDV is driven by the fact that vehicles are shifting from hardware-centric products to software-centric platforms. The value of a vehicle is now determined by the addition and improvement of functions through software, and we have entered an era where software influences the entire vehicle lifecycle, from driving performance and driver assistance to comfort features and even continuous updates via OTA (Over-the-Air).
Furthermore, there is a growing demand for architectures that are not based on individual vehicles but on connectivity with the cloud and other vehicles. This has led to an increase in development requirements that cannot be met by conventional methods, such as flexibly reconfigurable ECUs, integrated zone architectures, and parallel development of large-scale software. Compliance with safety standards and cybersecurity regulations (ISO 26262, ISO/SAE 21434, UN-R155/R156) progressing in various countries also necessitates mechanisms for continuously updating software and maintaining security.

Due to these environmental changes, the following requirements have become common challenges for all OEMs and Tier 1 suppliers.
- ECUs become more functional and integrated as E/E architectures evolve.
- Strengthening compliance with functional safety (ISO 26262) and cybersecurity (ISO/SAE 21434)
- Reduce time to market and maximize development efficiency

On the other hand, the requirements from OEMs are becoming more sophisticated and complex year by year. There are limits to what we can handle with our own resources alone. It's starting to become visible.

Macnica 's Solution Examples

We offer microcontrollers and development environments tailored to your specifications.

Infineon
AURIX ™ microcontrollers feature a multi-core configuration and lockstep, delivering high performance while also meeting the demands for high reliability and safety through compliance with standards such as HSM (Hardware Security Module) and ISO26262. Combined with the expansion of the lineup to include ARM-based medium-to-small-sized microcontrollers like TRAVEO T2G ™ and Automotive PSOC4 ™, Infineon has established itself as the world's No. 1 in automotive microcontroller sales as of 2025. In the Japanese market, Infineon has a long track record of adoption, and many customers have adopted its MCUs as they meet the required specifications for automotive control. With the reusability of development environments and software assets, a wide variety of evaluation boards are available for each product and application for feasibility studies.

Macnica unique technical support, leveraging tools from various companies as assets - Model Based Development -

Here, we will introduce one of our assets: the construction of control models using a Model-Based Development (MBD) environment, and a demonstration using an automated code generation function.
We are building a BLDC motor rotation control demo using the AURIX ™ evaluation board, utilizing MathWorks MATLAB/Simulink and Embedded Coder, and Tasking 's SmartCode.
By adopting MathWorks tools, you can easily build control models in the same environment by utilizing the Hardware Support Package (HSP) for AURIX ™.
The verified control model is output as C code using an automatic code generation function, and the functionality is realized by writing it to the MCU in cooperation with a compiler.
The benefits of implementing MBD development tools are as follows:

On a project basis OEM I've heard that it's not uncommon for companies to request a model during the acceptance testing process.
Macnica believes that one of the contributing factors is that Model-Based Design (MBD) development is becoming a common language in the automotive market.

Therefore, in order to eliminate the challenges that customers face in setting up and implementing this environment, Macnica has built an environment that allows for prior verification.
By working closely with our partner companies, we have established a support system that assists clients from consulting to implementation.

The value Macnica provides

This article presented examples of solutions to address challenges in development.
This is just one example, so if you have any development challenges other than MBD, please feel free to contact us.
