Highly Accelerated Life Testing (HALT) and Highly Accelerated Stress Screening (HASS) are often used to detect faults in electronic systems, testing the extremes and determining the outer limits of system margins. All hardware components and systems will eventually fail under environmental stress. But can this technique be used to improve software reliability as well?

Embedded run-control (aka on-chip debug, or processor debug port control) has numerous benefits in the areas of test and debug, for Design Engineering, Manufacturing Test Engineering, and Field Service. What are they?

What is Board Bring-Up, and why does it take so long?

Board bring-up is a phased process whereby an electronics system is repeatedly tested, validated and debugged, in order to achieve readiness for manufacture. This process can take so long that a product never gets to market because it is succeeded by the next generation...

I was reflecting on how much processor speeds, memory, and data transmission rates have increased over the last few decades. And yet the same old tools and techniques are often used to bring up new designs. When do you think we fall off the cliff?
