Introduction

The automotive industry is transforming, shifting vehicles from being primarily mechanical systems to software-defined, connected platforms where communication speed, reliability, and security are mission-critical. At the heart of this shift lies Automotive Ethernet, the backbone technology that enables everything from advanced driver assistance systems (ADAS) and autonomous driving to high-definition infotainment and over-the-air (OTA) updates.

In this transformation, Comcores has established itself as the one-stop shop for Automotive Ethernet networking, delivering digital IP building blocks and subsystems for both ASIC and FPGA-based systems. By offering a complete and standards-compliant portfolio of Ethernet IP and software, integrated with robust security solutions, Comcores enables OEMs and Tier 1s to design future-ready platforms with confidence.

Why Automotive Ethernet Matters

Traditional in-vehicle networking technologies like CAN, LIN, and FlexRay cannot handle the massive data requirements of modern vehicles. Automotive Ethernet overcomes these limitations by delivering:

• High bandwidth from 10 Mbps to multi-Gbps for data-heavy applications like sensor fusion.
• Time-Sensitive Networking (TSN) to guarantee deterministic, low-latency communication for safety-critical domains.
• Scalability and flexibility across entry-level and premium vehicle platforms.
• Standards-based design, ensuring interoperability and cost efficiency across the supply chain.

By combining performance, determinism, and scalability, Automotive Ethernet has become the unifying communication backbone for next-generation vehicles.

Comcores: A Complete Portfolio of Ethernet and Security Solutions

Comcores is recognized as the market leader in Automotive Ethernet and security, providing the most comprehensive set of digital building blocks and subsystems to support all stages of design and deployment for ASICs based solutions as well as FPGA reference platforms.

Ethernet Building blocks

• 10M-2G5 End-stations or bridged end-stations compliant with TSN Automotive profile (IEEE802.1DG) and Open Alliance work groups. End-stations are self contained and comes with SW-stack for easy integration into automotive use cases.
• Switching and gateway TSN-enabled solutions compliant with IEEE 802.1 standards, and providing the smallest footprint in the industry and largest feature set and functionality for building the key nodes of your automotive network.
• Flexible and scalable implementations tailored for both resource-constrained ECUs and high-performance central compute nodes.

Security Solutions

• MACsec (IEEE 802.1AE) IP for encryption and authentication of Ethernet traffic.
• Hardware Secure Modules (HSM) for root of trust
• Additional cryptographic modules for secure communication aligned with UNECE WP.29 and ISO/SAE 21434 cybersecurity requirements.

Software and Integration

• Full-featured software stacks and drivers that ensure seamless integration with the hardware IP.
• A holistic approach that reduces complexity, accelerates time-to-market, and minimizes integration risk.
• FPGA based boards for rapid testing of the Ethernet solutions in existing products

This combined offering makes Comcores a true one-stop shop, delivering not just individual IP blocks but complete Ethernet subsystems ready for automotive integration.

Standards Compliance and Interoperability

Comcores’ solutions are engineered to meet the strict requirements of the automotive industry:

• Open Alliance compliance: Ensuring interoperability and industry acceptance across the global supply chain.
• IEEE 802.1 TSN standards: Including the automotive TSN profile (IEEE 802.1DG), enabling deterministic, real-time Ethernet communication for safety-critical systems.
• Automotive-grade robustness: Designed to meet ISO 26262 functional safety requirements.

By adhering to these standards, Comcores ensures that its solutions integrate seamlessly into the automotive ecosystem, providing OEMs and Tier 1s with a future-proof and compliant networking foundation.

The Bigger Picture: A Secure, Connected Future

Automotive Ethernet is more than just speed—it’s about enabling secure and deterministic communication between the growing number of ECUs, sensors, and gateways inside the vehicle.

Comcores’ complete Ethernet and security portfolio provides:

• Deterministic communication through TSN.
• Secure communication with MACsec and advanced cryptography.
• Subsystems and software that deliver a ready-to-deploy solution.

This positions Comcores as more than a technology provider: it is a strategic partner, enabling OEMs and Tier 1s to build the ASICs required to realize the vision of fully connected, software-defined, and autonomous vehicles.

Conclusion

As vehicles evolve, Automotive Ethernet is becoming the central nervous system of new generations of automotive platforms with a security overlay on top.
