Designed to be future-proof and offering an extensive features set, the QUATTRO is able to support automotive developments up to the L5 autonomy and complements the existing third-generation logiRECORDER data logger that will be actively maintained and upgraded for use in performance and cost-optimised automotive developments.
The QUATTRO offers 128 Gbps of data logging and playback bandwidth, up to 128 TB of internal data storage and enables direct connections of up to sixteen (16) video cameras, with resolutions up to 32 MP, via current LVDS interfaces, such as GMSL2 from Analog Devices or FPD-Link III from Texas Instruments.
According to Xylon, it is already working on support for next-generation LVDS interfaces. XYLON QUATTRO is backwards compatible with the existing logiRECORDER video I/O modules, which assures users of immediate support for different video interfaces.
High-end LIDAR and RADAR sensors, as well as many other automotive systems can be directly interconnected via up to sixteen (16) 10M/100M/1G/2.5G/10G Ethernet (BASE-T) and Automotive Ethernet (BASE-T1) channels. Four-channel Ethernet modules can be configured into the fastest, HW-based two-channel TAP configuration, thus eliminating the need for expensive external Ethernet switches.
QUATTRO can directly interface, without external converter boxes, more than twenty (20) low and mid speed automotive interfaces, including different versions of CAN, LIN, UART and FlexRay networks. It complements the device’s high-speed data logging and playback to enable a complete collection of centrally timestamped vehicle data.
"We consulted with practically all Tier1s, OEMs, as well as with many technology and AI companies on their current and future needs”, said Xylon's founder and CEO Davor Kovacec. "Taking everything into consideration, we were able to create a universal, multifunctional device capable of fulfilling all test tasks in the years to come. The new and open SW architecture paired with configurable HW enables customers to tailor tests to virtually any user case."
The key QUATTRO differentiator is, according to Xylon, its programmable hardware engine configurable at the FPGA chip level. Custom designed hardware enables data processing out of reach to software or common hardware-based processing engines, such as real-time insertion of a “live” video camera’s metadata into synthetically generated camera data for HIL testing of an ECU under test that runs the production firmware mode.
Xylon has also expanded the HW engine with a complete x86-based PC to offer new possibilities in data logging and HIL playback, AI triggering and filtering, automated scripted testing, etc. The company has heavily invested into an open software architecture to enable user customisations and modularity.
In HIL setups, Xylon systems work as smart I/O boxes that convert synthetic data from multiple and heterogeneous vehicle sensors modelled within the simulation platform into physical automotive interfaces connected to real ECU and domain controllers under test. This real-time interface between the synthetic and real world works in both directions and enables full virtual test drives. While the third generation data logger has a single 10 GbE HIL port, QUATTRO integrates two (2) 100 GbE HIL ports to enable the most complex simulations like ECU perception algorithms checkup based on simulated high-resolution camera and LIDAR inputs.
Xylon plans to start shipping the QUATTRO to selected customers by the end of 2Q2023, with full production planned for 3Q2023.
