JTAG is coming up on its 30th anniversary. And some would say it’s older than that. As I prepared for doing an introductory presentation on this amazing technology, I got a chance to reflect on how useful it has become, and what the next 30 years might be like.

In Part 3 of this series, I looked at the JTAG scan path of the ASSET ScanLite demo board, and explored some of the fundamentals of IEEE 1149.1. This week, I do some fault insertion on the scan path, and see how that is detected by boundary scan.

I’ve gotten all of my Christmas shopping done early, so I managed to make some time for exploring our ScanWorks test tool. I’m taking a “newbie approach” to using the tool, initially for hacking around with boundary-scan test. There’s some pretty cool technology here.
