Category: 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.
Embedding JTAG into a system’s service processor allows for powerful out-of-band (independent of the operating system) built-in self test (BIST) functions. Using JTAG-based boundary scan, for example, can isolate system failure root cause to an extent unachievable through any other means.
