Interoperability Testing

方案介绍

Interoperability Tests is part of Test Scope Layer 1 of Automotive Ethernet defined by TC8 Test Specification
互操作性测试是Open Alliance定义的TC8测试规范中的一部分,属于物理层测试。

100BASE-T1 Interoperability Tests includes following 3 aspects:
100BASE-T1互操作性测试包含下面三方面内容
  • Link-up Time 连接时间
  • Signal Quality 信号质量
  • Cable Diagnose 线束诊断
具体而言,包含如下Test Case (TC8 V2.1)
  • Link-up time
    LINKUP_01    Link-up time - Trigger: Power on Golden Device
    LINKUP_02    Link-up time - Trigger: Power on ECU
    LINKUP_03    Link-up time - Trigger: Wake up ECU
    
  • Signal Quality
    SIGNAL_01    Indicated signal quality for channel with decreasing quality
    SIGNAL_02    Indicated signal quality for channel with increasing quality
  • Cable diagnostics
    CABLE_01     Cable diagnostics for ground detection
    CABLE_02     Cable diagnostics for near and far end open
    CABLE_03     Cable diagnostics for near and far end short
Technica提供完整的解决方案以完美实现车载以太网TC8中的IOP测试,配置方案由三部分组成
  • Golden Device
  • ANDi Software
  • ANDi-IOPT Add-on
如果要在信号质量测试中,使用高斯噪音Gaussian Noise实现Artificial Signal Degradation ,我们推荐使用R&S的RTO-B6来产生噪音,并通过RT-ZF7 set作为耦合器。
