Hot swap data logger for Software Defined Vehicle verification and validation

TTTech Auto has introduced a cutting-edge data logger tailored for Software-Defined Vehicle (SDV) verification and validation. The PM-350 Automotive Data Logger is specifically designed to capture signals from an Automotive Ethernet 100/1000Base-T1 bus with precise, synchronized data capture using centralized timestamp resolution below 100 ns.

This advanced technology ensures vehicle safety by eliminating interference on the communication level. Moreover, the data logger supports the logging of traditional interfaces such as CAN FD, LIN, and FlexRay.

• NXP to acquire TTTech Auto for $625m
• Three teams collaborating on SDV software stack
• Rebranding efforts for software-defined vehicles

One of the primary challenges in software-defined vehicle designs is capturing and storing data across all buses. To address this, the PM-350 is equipped with two NVMe M.2 SSDs, each offering up to 4TB of industrial-grade storage for high recording rates while minimizing power consumption.

Additionally, the data logger features a hot-swap capability, allowing users to seamlessly exchange SSDs during active sessions without disrupting operations or risking data loss.

With an onboard keypad and display, the PM-350 is expandable through various capture modules, providing flexibility and scalability for different testing scenarios.

“The launch of the PM-350 represents a significant milestone in our dedication to advancing automotive data logging technology. This device sets a new standard for capturing high-speed Automotive Ethernet signals, ensuring vehicle safety by eliminating communication interference and enabling seamless SSD exchange with hot-swap functionality. We believe that the PM-350 will empower our customers to achieve exceptional performance and flexibility in their software-defined vehicle testing and fleet management operations,” stated Lars Schöffel, Product Manager Data Logger at TTTech Auto, which is set to be acquired by NXP Semiconductors.

The PM-350 data logger is fully programmable with an open API and diagnostic protocol support for SDV functional testing, fleet management, and test drives. Its software-defined device configuration allows for remote data analysis and distribution, and it can be used with cascading devices featuring unique timestamps.
