Challenges Of Logic BiST In Automotive ICs


The electronics in passenger cars continues to grow, and much of it is bound by the strict functional safety requirements formalized in the ISO 26262 standard. The ICs that drive the electronics systems in automobiles are also increasingly complex, designed to execute artificial intelligence algorithms that govern emerging self-driving capabilities. Designers are quickly adopting comprehensi... » read more

Meeting ISO 26262 Requirements Using Tessent IC Test Solutions


As the industry moves towards greater automation in vehicles, suppliers of the ICs used to drive the automotive electronic systems are rapidly adopting solutions to meet ISO 26262 requirements. The Tessent family of IC test products offers the highest defect coverage, in-system non-destructive memory test, hybrid ATPG/Logic BIST, and analog test coverage measurement.

Improving In-System Test With Tessent VersaPoint Test Point Technology


This paper describes a new versatile test point technology called VersaPoint, which has been developed specifically to work with designs implementing mixed EDT/LBIST methodologies to reduce EDT pattern counts and improve Logic BIST (LBIST) test coverage. VersaPoint test points can reduce compressed pattern counts 2X to 4X beyond compression alone and improve LBIST test coverage beyond what is p... » read more

Are Chips Getting More Reliable?


Reliability is emerging as a key metric in the semiconductor industry, alongside of power, performance and cost, but it also is becoming harder to measure and increasingly difficult to achieve. Most large semiconductor companies look at reliability in connection with consumer devices that last several years before they are replaced, but a big push into automotive, medical and industrial elec... » read more
