Top Electronic and Electrical System Design blog posts of the past year
At the start of a new year, it’s the perfect time to look back at the standout Capital electrical system design blog posts of the past twelve months. The past year brought significant innovation alongside major shifts across the industry, and we have worked hard to reflect this through our posts.
Join us in revisiting the most impactful posts that have informed and inspired our community over the past 12 months. Here’s to celebrating the achievements of 2025 and welcoming the opportunities of the new year. Happy New Year!
1. Siemens and Infineon Advance the Software‑Defined Vehicle
As automotive OEMs transition toward software‑defined vehicles (SDVs), they face increasing demands for performance, safety, and development efficiency. Siemens Digital Industries Software and Infineon Technologies addressed these challenges by announcing an expanded collaboration that delivers production‑ready embedded software for Infineon’s AURIX™ TC4x microcontroller family.
By integrating Siemens’ Capital™ Embedded AR Classic platform, based on AUTOSAR Classic R20‑11, with Infineon’s high‑performance AURIX TC4x MCUs, the companies enable scalable, safety‑certifiable ECU software development. This integrated solution supports the multicore processing, functional safety, and cybersecurity capabilities required for advanced applications such as ADAS, electrification, and next‑generation E/E architectures.
The collaboration has already demonstrated production readiness with lead customer BMW, leveraging a cloud‑based development process to streamline software delivery. Together, Siemens and Infineon are helping OEMs reduce complexity, improve time to production, and establish a robust foundation for the future of the software‑defined vehicle.

2. Embracing SaaS to Modernize Aerospace Electrical System Design
The aerospace industry is undergoing rapid transformation driven by electric and hybrid aircraft, advanced avionics, and increasingly complex E/E systems. To keep pace, aerospace OEMs and suppliers must balance innovation, regulatory compliance, and cost efficiency, often across globally distributed teams. Cloud‑based Software‑as‑a‑Service (SaaS) models are emerging as a critical enabler of this shift.
Through Capital X, Siemens delivers a SaaS‑based E/E systems development environment that leverages the digital twin and digital thread to virtually design, analyze, and validate aerospace electrical systems before physical implementation. This approach helps teams reduce design iterations, manage rising system complexity, and improve overall reliability.
SaaS also enables real‑time collaboration, scalable computing resources, and robust data security. By moving aerospace electrical design to the cloud, engineering organizations can accelerate development timelines while maintaining the safety, compliance, and traceability required for next‑generation aircraft programs. Our blog post goes into more detail, and you can download a free eBook on this topic here.
3. Transforming E/E Design Workflows with Styling in Siemens Capital
As E/E system complexity increases, engineering teams need clearer, more efficient ways to work with shared design data. Styling in Siemens Capital software addresses this challenge by enabling role‑specific, customizable diagram views while preserving a single source of truth.
Capital’s styling capabilities allow the same underlying design data to be presented differently for engineers, manufacturing teams, and downstream stakeholders—without duplication or rework. This flexibility reduces manual effort, improves consistency, and supports compliance with corporate and industry standards.
By separating data from visualization, Siemens Capital helps organizations improve collaboration, streamline workflows, and ensure accurate communication across the product lifecycle, ultimately increasing efficiency and design confidence. Read all about it here.
4. Accelerating Automotive E/E Design with Cloud‑Based Engineering
Much as we already spoke about the changes in aerospace and defense, automotive E/E system development is also increasingly complex. To shorten development cycles while supporting global collaboration, Siemens discussed the benefits of Capital X cloud‑based SaaS solution. By leveraging the digital twin and digital thread in the cloud, teams can explore architectures, validate designs early, and collaborate seamlessly across locations. The result is faster innovation, improved scalability, and a streamlined path from concept to production. Learn more here.
5. Streamlining AUTOSAR Integration with Siemens Capital Embedded Integrator
As software‑defined vehicle programs grow in complexity, integrating AUTOSAR‑based embedded software has become a critical bottleneck. Siemens Capital Embedded Integrator addresses this challenge by providing a connected, automated approach to AUTOSAR Classic Platform integration.
The solution reduces manual rework by automating a significant portion of basic software configuration while maintaining end‑to‑end traceability across requirements, software architecture, and configuration data. By importing and synchronizing AUTOSAR artifacts within a guided workflow, teams can accelerate integration, improve quality, and enable continuous validation early in development. Read our post to see how Siemens Capital Embedded Integrator helps automotive teams deliver embedded software faster, with greater confidence and scalability in modern E/E architectures.
As we close the chapter on 2025, these standout posts highlight how rapidly electrical and electronic systems engineering continues to evolve. From cloud‑enabled workflows and embedded software integration to design automation and collaboration at scale, the past year showcased both the challenges engineers face and the technologies helping them move forward. We look forward to building on this momentum in the year ahead and continuing to share insights, innovations, and practical guidance that support our community as it navigates increasing complexity and embraces the next wave of digital transformation in E/E systems design.
