IEEE P1687 Internal JTAG (IJTAG) taps into embedded instrumentation

There’s a wealth of test and measurement IP trapped
inside chips and it’s ready for the IJTAG standard to set it free. When that
happens, you’ll be able to validate, test and debug circuit boards and systems
better. The IEEE P1687 Internal JTAG (IJTAG) working group has been toiling
away for several years now, codifying an open industry standard for accessing,
managing and automating the operation of embedded instruments. Recently, we
published a white paper about IJTAG, “IEEE P1687 Internal JTAG (IJTAG) taps
into embedded instrumentation.”


You might be
wondering: What do instruments embedded on chips for chip test have to do with board and system validation, test and debug? And
why is another standard needed? Our IJTAG white paper will help you understand.
Managing and coordinating multiple on-chip instruments has been extremely
complex. IJTAG helps makes sense of it. Then there are the many benefits of
instrument portability and re-use. IJTAG goes a long way toward building an
ecosystem around embedded instrumentation because – for the first time – instruments
will be portable from any chip and board design to the next, and you’ll be able
to use the same standards-based toolsets no matter where the instruments are.
