Replay and HIL AD Reference Architecture Overview

The Replay and HIL AD Reference Architecture provides a pattern for designing PXI-based systems that test ECUs for advanced driver-assistance systems (ADAS) and autonomous driving (AD).

Replay and HIL AD Key Features

The features that set Replay and HIL AD apart:

  • Precise timing and data synchronization
  • Low-latency data transfer API for communication between microservices
  • RDMA support for high-bandwidth data transfers, such as camera image data
  • Modular off-the-shelf hardware for future I/O and test requirements expansion
  • Unified test system architecture to switch between data replay and HIL test
  • Dynamic test case manipulation for fault insertion
  • Diagnostic tooling for determining latency and throughput

Replay and HIL AD Requirements

Your Replay and HIL AD system must meet the following minimum requirements.

  • NI requires using one of the following chassis (must include the Timing and Synchronization chassis upgrade):
    • PXIe-1092
    • PXIe-1095
  • NI requires using one of the following controllers:
    • PXIe-8862
    • PXIe-8881
  • NI requires using one of the following operating systems:
    • Windows 10 (for development and deployment)
    • Ubuntu 20.04 (for development and deployment)
    • Ubuntu 22.04 (for development and deployment)
    • NI Linux® Real-Time (for deployment)
