Case Study: BYD Automotive achieves 50% faster Automotive Ethernet testing and reduced BOM costs with Keysight

BYD Plans For Growth With Faster Automotive Ethernet Testing

BYD Automotive, one of China’s largest automakers, needed to replace its legacy CAN network with Automotive Ethernet (IEEE AVB/100Base‑T1) to support real‑time audio/video, diagnostics, software updates and multi‑vendor ECU interoperability while lowering costs. Keysight provided physical‑layer test instruments (including the DSO9404A oscilloscope and E5063A vector network analyzer) as part of the validation effort alongside partner test solutions.

Working with Ixia, Keysight delivered an end‑to‑end Layer 1–7 testbed—combining Keysight physical test components with Ixia’s IxNetwork and IxANVL—to automate PHY validation, protocol conformance and application testing. The Keysight solution cut BYD Automotive’s test time by 50%, enabled more than 600 OPEN Alliance conformance tests (over six times competitors), simplified automated testing from PHY to application, and supported a move to IEEE Automotive Ethernet that reduced BOM costs and improved part availability.
