Next-Generation Vehicles Pose Automotive Semiconductor Test Challenges

The impact of zero defects on test coverage and cost.

popularity

Various market trends are driving requirements for automotive semiconductor test as technology increasingly defines the future of the automobile. According to IHS Markit, the total market for semiconductors, having reached nearly $500 billion in 2018, will grow at a CAGR of 4.88% through 2022, while the automotive electronics category, reaching more than $40 billion in 2018, will outpace the total market, growing at a CAGR of 8.74% through 2022.

This market growth accompanies a paradigm shift toward the technologies that define the future of next-generation vehicles.

Alternative propulsion systems include hybrid and EV drivetrains and will require a new charging/refueling infrastructure, possibly including wireless charging, and will be accompanied by efficient motor drives, car weight reduction, and a move to 48-V batteries. To ensure high quality, it will be necessary to thoroughly test sensors, MCUs, power devices, power-management ICs, and other related components.
