logiRECORDER 3.5 is a high-performance automotive HIL video logger that combines raw multi-sensor data acquisition, synchronized playback, and real-time data injection into a single FPGA-based platform. Designed for ADAS and autonomous driving development, it enables deterministic recording and replay of video, Ethernet, radar, LiDAR, and in-vehicle network data through native automotive interfaces. Its modular architecture, scalable bandwidth, and comprehensive software suite accelerate ECU validation, Hardware-in-the-Loop testing, and data-driven vehicle development while reducing testing complexity and cost.
