As a diagnostic software engineer and an automobile enthusiast that drives a Yukon Denali (read: lots of electronics) I can see where this is a complex job and one that is very dependent on the initial design. If one assumes that the electronics are going to work, it makes diagnosis and testing that much harder. This is because the "failure" symptom is hidden at best, unknown at worst. Fault injection, as mentioned, is very limited and does not (probably) occur once the electronics are installed in the vehicle. So, really, no-one knows how it will really fail during operation, and the limited testing that is done during manufacturing is only going to catch gross/catastrophic issues. So, unless the design has built in status states, operation mode signals, or other active operation "displays", reverse engineering a test diagnsotic is very limited and does not scale well to increase its minimal coverage. Somewhere between the current automotive design and the airline or NASA Space Shuttle is a happy and affordable medium.

LATEST ARCHIVED BROADCAST
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
