Replay · ADAS/AD HiL Solution
Bringing Datacenter Performance to HiL
The b-plus HiL Solution combines powerful hardware and software building blocks with comprehensive engineering expertise for the validation of complex, data-intensive systems.
HiL Solution Engineering
From Individual Building Blocks to a Complete HiL System
b-plus develops tailored validation solutions for customer-specific DUTs, interfaces, data formats, network architectures, and workflows. The SDBI Station provides the central hardware platform for high-performance data transfer and injection. Depending on the project, the scope ranges from individual building blocks to a fully integrated and automated system.
The modular architecture supports single-ECU, multi-DUT, and data center setups. Hardware and software resources can be expanded and reused across applications and projects.
Data Center Performance for HiL
b-plus combines data center technologies with deep engineering expertise to create highly scalable HiL solutions for data-intensive validation. The central hardware platform is the SDBI Station.
Scalable and Cost-Efficient
Reusable HiL resources across ECUs, applications, teams, and projects improve resource utilization and reduce lifecycle costs.
From Building Blocks to Complete HiL Systems
b-plus delivers modular HiL solutions at the integration level that best suits each customer project, ranging from individual hardware and software building blocks to fully integrated validation systems.
Why an Integrated HiL Solution?
Validate Complex Systems Reproducibly
A DUT does not operate in isolation. Operating states, communication partners, data streams, networks, and timing dependencies must be brought together within the HiL setup.
- Enable DUTs for HiL: Establish operating states, diagnostics, communication, and dependencies.
- Handle Data-Intensive Scenarios: Provide high bandwidth and low latency for open- and closed-loop operation.
- Generate Validatable Results: Capture, correlate, and evaluate DUT responses synchronously.
- Scale Without Changing Platforms: From individual ECUs to multi-DUT and data center setups.
