At the IEEE European Board Test Workshop held in Tallinn, Estonia, May 2005,
a group of 14 board test professionals met to discuss a common set of problems
associated with the extended test and configuration use of 1149.1 boundary-scan
infrastructure within complex multi-board systems. As a result of this discussion,
it was decided to create a system-level JTAG initiative, called System JTAG (SJTAG).
It also was decided to create a white paper to more clearly define the nature of
these problems and hence their possible solutions.
