Learn about the overview of 10BASE-T1S and zone architecture in 1.5 hours. From the physical layer to PLCA, including key points of zoned testing.
[Target Audience] - Individuals responsible for design, evaluation, and testing related to in-vehicle networks (CAN/LIN/FlexRay/automotive Ethernet) - Development and verification personnel considering the transition to SDV/zone architecture - Those who have "heard of 10BASE-T1S but want to organize the mechanisms and testing perspectives" [Overview] In this seminar, we will cover the basics of automotive Ethernet and organize the aims and features of 10BASE-T1S (multi-drop, background of cost reduction), explaining the operating principles centered around the physical layer (DME), PLCA (collision avoidance), and transmission cycle. Furthermore, we will understand what changes with the transition from domain to zone and how testing and data observation become more challenging, along with specific examples.
