Issue 6 - February 2009

From the Chair

The group has settled into the new regular meeting time of 10:30 Eastern on Mondays and this is having the desired effect of improving the attendance on the calls

This has been further bolstered by a few new members, and I say "Welcome!" to our colleagues from Corelis. We are always ready to accept new members, and welcome the broadening of perspective they bring.

So, if you have an interest in system-level JTAG, even if you feel you're a "novice", then please join us. We would especially welcome applications from people in industry sectors not already represented by our existing membership.

Any comments on this newsletter can be mailed to admin@sjtag.org.

2009 Survey

During the summer of 2008, many of you will have filled out a simple survey on SJTAG, and will remember that we asked at that time for volunteers for a follow-up survey. We had planned on running that follow-up survey later in the year, but time and events got the better of us.

Well, the new survey is at last in preparation. This will be significantly more detailed investigation into current and prospective usage of JTAG within systems, and your co-operation will again be greatly appreciated.

If you want take part and didn't sign up through last year's survey then drop us a note using the Contact page on our website. For now though, you may want to take a quick look at the summary results of last years survey.

JTAG in Distributed Systems

The word "system" can be a rather amorphous term: For some, it may mean "System" on Chip, while for others an aircraft carrier is a "system". Certainly, it is the case that for many people, the term can refer to much more than just a single box of equipment.

Within the range of these definitions, the components of the system may be tightly coupled or widely distributed, and it is these distributed applications that are posing some interesting questions for SJTAG. In some examples, parts of the system may be quite remote from each other; mobile computing and cellphone technologies present some opportunities for such things as network diagnostics to be shared amongst all the users of the network.

What should SJTAG's role be in this? Is this a core technology that an SJTAG standard needs to support from the outset or is this a future extension to a standard? Sign up to our discussion forums, and give us your opinions.

System Data Elements

As part of our discussion on languages for SJTAG, we found we needed to describe the hierarchical nature of systems and we produced a UML (Unified Modelling Language) diagram to show this. However, we also felt that UML may not be very accessible for a lot of people so we produced this "friendlier" bubble diagram:

Small Bubble Diagram
