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

A Simple Way To Improve Automotive In-System Test


The remarkable growth in automotive IC design has prompted a focus on ISO26262 functional safety compliance, which includes both high-quality manufacturing test and a minimum stuck-at test coverage of 90% for in-system test. Designers must also control IC test data volumes, test application times, and test costs. A new test point technology that improves in-system test coverage and reduces patt... » read more
