Boundary scan is a method for testing interconnects (thin wire lines) on printed circuit boards
- Interconnect as in signal trace? --Abdull (talk) 20:21, 28 August 2008 (UTC)[reply]

Please merge boundary scan info from JTAG page into here...

There's a lot more to be said about boundary scan ... and it shouldn't be getting said on the JTAG page. -- 69.226.238.251 (talk) 04:27, 28 November 2009 (UTC)[reply]

I disagree - boundary-scan IS JTAG, on-chip debug etc..is not. Remember the acronym 'Joint Test Action Group' - no mention of debuggers. The JTAG committee that devised this system in the 1980s did so with boundary-scan in mind - nothing else. Additional chip features that are acccessd by the JTAG port are not part of any perceived JTAG standard and should not form part of this generic article. In my view all such separate debug interfaces (ARM, COP, MIP, and what have you) should be listed under separate articles. 195.60.15.185 (talk) 14:53, 3 December 2009 (UTC)[reply]

This article is about boundary scan. So why do you argue that details of boundary scan should not be in this article, dedicated to that topic?? Color me puzzled. JTAG certainly hasn't been limited to boundary scan for quite a few years now ... but digital boundary scan is fairly JTAG-centric. I only suggested that content be moved here, as part of improving this (pretty weak) boundary scan article ... not that JTAG for some reason be presented as not addressing boundary scan.

The JTAG article is covering the big picture of JTAG, which certainly includes debug as well as boundary scan. The ARM11 example just fleshes out that part of the skeleton. It's unlike boundary scan for several reasons ... including the obvious one, that boundary scan already has a dedicated (but weak and needs-improvement) page in WP. --69.226.238.251 (talk) 01:06, 9 December 2009 (UTC)[reply]

I moved the details and cleaned some of the transitions. This page still needs work, it's messy; but at least you don't have to go to another page to see most of the WP information on the topic of this page. --69.226.238.251 (talk) 19:26, 15 December 2009 (UTC)[reply]
