Planning Ahead For In-System Test Of Automotive ICs

Automobiles are increasingly more like electronic devices than mechanical platforms. As a share of the total cost of a car, electronics components have grown from about 5% in 1970 to 35% in 2010. Electronics are projected to account for 50% by 2030 (Deloitte, 2019). Some of the electronics are for passive operations, like display or In-Vehicle Infotainment (IVI) systems, but a growing proportio... » read more

Squeezing Out More Test Compression

The trend in semiconductors leads to more IC test data volume, longer test times, and higher test costs. Embedded deterministic test (EDT) has continued to deliver more compression, which has been quite effective at containing test costs. For many designs, standard test compressions is enough, but ICs for use in automotive and medical devices require a higher manufacturing test quality, which t... » read more

EDT Test Points

Embedded test compression was commercially introduced over a decade ago and has scaled to well beyond the 100X range envisioned when it was first introduced. However, growing gate counts enabled by new technology nodes as well as new fault models targeting defects within standard cells are driving the need for even greater compression levels. This paper describes an exciting new technology, cal... » read more
