Practical HIL Construction Strategy for Automotive and Off-Highway Controller Validation
Published2026.10.12 14:07As vehicle E/E architecture transitions to zonal structures and shifts to software-defined vehicles (SDV), the number of controllers (ECUs) requiring validation and software complexity are surging dramatically. Meanwhile, real vehicle testing cannot provide repeated verification under identical conditions and entails lead time and safety concerns. This white paper explains the principles of HIL (Hardware-in-the-Loop) validation and the structure of the NI platform composed of PXI, SLSC, and VeriStand, and through two actual implementation cases—Camera Record & Replay HIL for In-Cabin Monitoring Controller (ICMU) and Forklift Controller (VCU) HILS—describes how controller-level regression testing becomes possible. Additionally, it explicitly states application boundaries and limitations, such as lack of A2B support.

Color Accuracy Issues in Vehicle Interior Ambient Lighting and Intelligent LED Drivers
Vehicle interior ambient lighting is spreading across all price segments, and the level of color accuracy required of lighting designers is rising accordingly. This white paper quantitatively addresses why temperature drift and individual variations of RGB LEDs cannot be corrected by standard constant-current drivers, and explains an intelligent LED driver approach that integrates an MCU, calibration data, and a LIN network interface into the driver. It covers implementation details of the LITIX Interior TLD4020-3ET currently in production, portfolio roadmap, and evaluation/development environments, and clarifies application boundaries including lack of 48V support, lack of RGBi/ISELED support, and absence of direct optical degradation diagnostics.

Dual FOC Servo Drive Solution for Robot Hands and Humanoid Robots
The joints and hands of humanoid robots must densely pack multiple motor axes within extremely limited space. The conventional approach of using independent drives for each axis increases board area, heat dissipation, and wiring. This white paper addresses how STMicroelectronics solves this problem through a dual servo drive solution that simultaneously performs flux-oriented control (FOC) on two axes with a single controller (STSPIN32G4). Two patented technologies—shared current sensing (US Patent US 11,757,345 B2) and junction temperature measurement with thermal distribution layout (US 12,264,976 B2)—enabled a 150 W class dual board of 4 x 4.5 cm in size. Under 40 kHz current loop conditions during dual FOC operation, MCU load reaches a maximum of 60%, with the remaining computational headroom utilized for condition monitoring and AI-based automatic tuning. The solution's nature is a reference design rather than a finished product, with applicable boundaries and limitations specified in the text.

Arduino UNO Q Technical Whitepaper: MPU·MCU Hybrid Board for Cloud-Free Edge AI
Arduino UNO Q is a product that integrates a Qualcomm Dragonwing QRB2210 microprocessor (MPU) running Debian Linux and an STM32U585 microcontroller (MCU) executing Arduino sketches on Zephyr RTOS into a single UNO form factor board. The two processors do not share RAM and resources, exchanging data only through remote procedure calls (RPC) of Arduino_RouterBridge, and the development environment Arduino App Lab and apps reside within the board. This whitepaper describes the design intent of this hybrid architecture, development workflow, hands-on verification results, and limitations in industrial application based on webinar presentation materials and technical Q&A.

Design Solutions for Implementing High-Efficiency Industrial Drives
Industrial electric motors are projected to consume approximately 9500 TWh of power by 2030, representing about 30% of global electricity demand. If approximately 10% of energy can be saved in motor drive systems, it would be equivalent to meeting the power demand of all electric vehicles worldwide in 2030. This white paper, based on webinar presentation materials and technical Q&A, organizes the selection criteria for Si IGBT, SiC, and GaN switching technologies starting from the different requirements of servo, general-purpose, and medium-voltage drives, the trade-offs of each selection, improvements in TRENCHSTOP IGBT7, and reference designs that accelerate design verification.

Beyond Connectors, Going Contactless: 60 GHz Ultra-Short-Range Wireless Link ST60
Physical connectors linking devices and boards face limitations including wear, conflicts with sealed enclosures, and mechanical constraints on rotating parts. ST60 addresses this not through a general-purpose wireless protocol but by replacing the connector itself with a 60 GHz point-to-point link. As a result of choosing to tunnel signals directly without a protocol stack, it achieves propagation delays in the order of nanoseconds and power efficiency at pJ/bit levels, while sacrificing communication distance (maximum ~5 cm) and error recovery and adaptive control functions. This white paper organizes the structure, operating principles, design boundaries, and development environment of the ST60A2 and ST60A3 product families based on webinar materials.
