Addressing the automotive security
and safety challenge
Tessent Embedded Analytics technology provides a powerful platform for developers who need to ensure the security and functional safety of their products – particularly in the automotive industry.
Our semiconductor IP can improve verification and validation during product development; and it can be used in deployed products to spot both systemic and random errors, providing a new level of safety functionality, and allowing in-field system health monitoring and advanced forensics.

Webinar: Effectively Addressing the Challenge of Securing Connected and Autonomous Vehicles
As vehicles get more complex and connected, the attack surface increases. This presents increasing challenges for cybersecurity. This webinar on 7 October 2021 introduces hardware-based techniques for addressing security concerns, from legacy through to the future.
Security matters: hardware-based analytics and ISO21434
Our new white paper covers the changing face of engineering for safety and security and the emerging ISO21434 cybersecurity standard. We examine the development process – including risk assessment, threat analysis, and security planning – and also look at hardware-based monitoring systems that provide an additional root of trust, and react in microseconds rather than milliseconds.

Security & functional safety in hardware
Our downloadable brochure gives an overview to the benefits of Embedded Analytics in automotive applications
Our customers use Tessent IP in a variety of applications:
- System-wide run/control of a video processor
- Multi-core safety-critical system, including deadlock detection and lock-step monitoring
- Debug, optimization and in-life monitoring LIDAR
- Control system for electric motors, battery and energy management systems
ISO26262 compliance: and more
The Tessent Embedded Analytics infrastructure is independent of the main system and non-intrusive, and so can be deployed as a Safety Element out of Context (SEooC) in ISO26262 terms. It provides information and analysis that allow designers to more easily satisfy the functional safety, risk assessment, testing, reporting and traceability requirements of standards such as ISO26262, IEC 61508, EN50126/8/9 and CE 402/2013. In the same way, we also facilitate the move to security standards such as SAE J3061.
Edition 2 of ISO26262 includes more detail on requirements for semiconductors, in the form of a new “Part 11”, including ISO/PAS19451. With the move towards ever more safety-critical functions, such as automated driver assistance systems (ADAS), these requirements are becoming ever more important.
The Tessent Embedded Analytics architecture includes features specifically optimized for safety and security, including:
- Lockstep monitor, allowing consistency checking between redundant modules. The monitor is CPU-independent, requiring no native support, and can be extended to other error tests and voting systems.
- Bare Metal Security, providing a hardware-based level of security “below the operating system”. BMS is extremely difficult for an attacker to detect or subvert, and supports the requirements of SAE 3601 cybersecurity for automotive.
