ICT for Automotive Industry

This document discusses challenges in circuit testing for the automotive industry and how Agilent has addressed them. It outlines four main challenges: 1) larger boards and faster cycle times, 2) larger ICs with increased functionality, 3) mandatory on-board programming, and 4) worldwide deployment management. The document then explains how Agilent has solved these challenges through technologies like test point accessibility solutions, scalable testing platforms, and features that improve throughput.
