Seung-taek Jang, Director at Keysight Technologies, presented at e4ds Tech Day 2026 on the topic of "Beyond Complexity to Confidence: Integrated V&V (Validation & Verification) Strategy for SDV Development," emphasizing that "the real bottleneck in SDV development is integration and verification, not development itself." In the SDV era, vehicle architecture becomes increasingly complex with OTA, cybersecurity, AI, V2X, and zonal architecture, with verification scope expanding beyond individual ECUs to the entire vehicle platform. Defects tend to occur at the boundaries between four domains—Automotive Ethernet, HPC, OTA, and V2X—making an integrated V&V system essential. The "Reusable Test Asset" that reuses identical scenarios from SiL to HiL through field testing and the Shift-Left strategy that advances verification to early stages determine SDV quality and cost competitiveness.
