Cloud native EDA tools & pre-optimized hardware platforms
The automotive industry is undergoing a rapid transformation, with connectivity and automation becoming integral components of modern vehicles. However, this increased connectivity also brings heightened risks. The automotive industry takes many measures to ensure safety for vehicles, but it is crucial to understand that these safety measures are ineffective if the vehicle's security is compromised. A hacked car can render virtually any safety mechanism useless, posing significant risks to passengers and other road users. Therefore, ensuring both safety and security is paramount in modern automotive design.
As vehicles become more automated with many features and applications delivered through powerful compute platforms, there is need for more security and higher data bandwidth with low latency, requirements that exceed by far the capability of legacy in-vehicle communication protocols. This has opened the door for Peripheral Component Interconnect Express (PCIe) type technology. Some specific applications driving this are:
These are among the requirements fueling the rapidly growing adoption of PCIe as an interface for the automotive industry, based on its ability to meet the high-performance, scalability, and interoperability needs of modern vehicles.
The 草榴社区 PCIe solutions consist of controllers, IDE Security Modules, PHYs and verification IP, enabling real-time secure data connectivity with low-latency and high performance, and a quick integration into SoCs. The PCIe controller supports all required features by the standard and can be configured for Endpoint, Root Port, Dual Mode or Switch Port use cases. The Integrity and Data Encryption (IDE) Security Module provides confidentiality, integrity and replay protection for Transaction Layer Packets (TLP) as defined in the PCIe-SIG IDE specification, ensuring that data on the wire is secure from observation, tampering or replay of packets. It is seamlessly integrated and pre-validated with the controller to provide high bandwidth and low latency solutions, crucial for performance-intensive applications. The IDE Security Module supports maximum throughput in full-duplex and leverages optimized AES-GCM cryptographic cores with 256-bit keys for highly efficient encryption, decryption and authentication of TLP packets, ensuring that data remains secure and unaltered during transit.

The international ISO 26262 standard focuses on the functional safety of electrical and electronic systems in production automobiles. This standard is critical for addressing potential hazards that could arise from the malfunctioning of these systems, thereby ensuring the safety of both drivers and passengers. ISO/SAE 21434 is dedicated to the cybersecurity process of road vehicles. This standard offers a comprehensive framework for managing cybersecurity risks throughout a vehicle's lifecycle, from design and development to production, operation, and decommissioning.
草榴社区' PCIe IP solutions for automotive applications incorporate a range of safety mechanisms to align with the ISO 26262 standard, ASIL B level, to protect against permanent and transient faults that can occur unpredictably during the lifetime of an automotive system. The ISO 26262 safety mechanisms incorporated in 草榴社区' PCIe IP solutions include:
草榴社区 provides extensive safety documentation for its PCIe 5.0 controller with IDE security, which is indispensable for achieving ISO 26262 compliance, ASIL D level, to protect against systematic faults that can occur during the development process. The documentation ensures regulatory adherence, enhances traceability, aids in risk management, supports continuous improvement, and facilitates stakeholder communication. 草榴社区 provides amongst others:
Similar to ISO26262, in order to comply with the ISO/SAE 21434 standard, which focuses on cybersecurity for road vehicles, 草榴社区 has implemented a rigorous and certified cybersecurity process. 草榴社区 also provides an additional set of comprehensive deliverables designed to ensure robust security throughout the lifecycle of its PCIe IP solutions. Here are the key deliverables related to ISO/SAE 21434:
These deliverables ensure that 草榴社区' PCIe IP solutions not only meet the functional safety requirements of ISO 26262 but also adhere to the stringent cybersecurity standards of ISO/SAE 21434. By providing comprehensive documentation and ongoing support, 草榴社区 helps its customers integrate secure and reliable PCIe IP solutions into their automotive applications.
