Similar But Different — The Tale Of Transient And Permanent Faults


When determining whether an IC is safe from random hardware faults, applying safety metrics such as PMHF, SPFM, and LFM, engineers must analyze both transient and permanent faults. This paper highlights the fundamental differences between permanent and transient faults on digital circuits, and why this distinction is important in the context of the ISO 26262:2018 functional safety standard. ... » read more

Reshaping Automotive Design


The entire automotive ecosystem is being reshaped by vehicle electrification, assisted and autonomous driving, and the connectivity needed to make it all work. So far, it's not clear just how smoothly this will all come together. In this redefined world, electronics and software will provide differentiation rather than mechanical engineering and possibly even brand name, creating change on a... » read more
