IEEE P1687 Internal JTAG (IJTAG) Taps into Embedded Instrumentation
For years chip vendors have embedded test and measurement instruments into their chips so that the chips themselves could be tested. Now, the industry has realized that this wealth of validation, test and debug instrumentation can be put to wider use on circuit boards and in systems. The new IEEE P1687 IJTAG standard is a step in this direction. This e-book describes the objectives of the IJTAG working group and the resulting IJTAG on-chip embedded instrumentation architecture.
