Chapter 10. Boundary Scan and Core-Based Testing

Kuen-Jong Lee

National Cheng Kung University, Tainan, Taiwan

About this Chapter

Boundary scan, also known as the IEEE 1149.1 or JTAG standard, appears to be the most successful test standard ever approved by the IEEE. Initially targeting board-level testing for digital circuits, this standard has now been adopted by industry for use in most large IC chips and has been used to access many other applications, including power management, clock control, debugging, verification, and chip reconfiguration. An extended boundary-scan standard for the I/O protocol of high-speed networks (namely, 1149.6) has recently been established, and it further enhances the applicability of boundary scan.

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
