Overcoming Challenges in Electric Vehicle Embedded Software
Development
As the transportation industry undergoes a shift towards electrification, vehicles must possess systems that are safe, reliable, and easy to use, placing immense pressure on engineers and software architects. All six components of the electric vehicle (EV) powertrain system must work in harmony to achieve optimal performance. However, there are several architectural challenges and considerations regarding safety and security in software development. Additionally, charging protocols vary by region and are constantly evolving. Due to the complexity of embedded software in electric vehicle (EV) electrical powertrains, automotive software developers require specialized solutions to address the intricate issues during the development process.
Siemens Digital Industries Software has released a white paper titled “Overcoming Challenges in Embedded Software Development for Electric Vehicles”, discussing issues related to EV electrical powertrains and software development, as well as how its comprehensive solutions assist developers in overcoming challenges in electric vehicle embedded software development:
• Key trends that help accelerate the development and use of EVs

Architectural, Safety, and Security Challenges of Electric Vehicle Embedded Software
It can be said that driving safety is the top requirement for all vehicles; with the introduction of high-voltage components, safety requirements for electric vehicles are becoming increasingly stringent. As more modern vehicles become connected and feature highly complex electrical architectures with numerous access points, electric vehicles are particularly vulnerable to cyber threats such as ransomware, malware, or distributed denial-of-service (DDoS) attacks, posing risks to personal data and payment information. Furthermore, electronic control unit (ECU) developers must strive to address new architectural challenges. While electric vehicles and plug-in hybrids on the market are quite mature, chargers and charging technologies continue to evolve, necessitating the use of communication stacks to develop ECUs to ensure compatibility between EVs and roadside EVSE.
Reducing Hardware Dependency through E/E System Development
Further complicating electric vehicle systems is the requirement that all components must meet specified Automotive Safety Integrity Level (ASIL) standards to ensure the safety of the entire system. For this purpose, a microcontroller with multicore support and an AUTOSAR stack, along with AUTOSAR basic software (BSW), will be very beneficial. AUTOSAR is a major standard in automotive software, with all major automotive OEMs and most tier-one suppliers participating in the development of the AUTOSAR standard. Siemens’ production-validated complete solution, which supports AUTOSAR, not only integrates, tests, and analyzes software but also reduces hardware dependency.
How Multicore Solutions Address Challenges in EV Embedded Software Design
Today, developing advanced automotive products for the future is inseparable from advanced integrated E/E system development tools. Capital VSTAR’s multicore solutions enable software distribution, which is particularly effective in overcoming performance and safety challenges in EV embedded software design. It also provides a solution to address security challenges in software platform development, powering high-performance ECUs in today’s electric vehicles.
