JTAG
Figure 9: JTAG Block Diagram
Microprocessors and Application Specific Integrated Circuits (ASICs) pose many design
challenges, not the least of which concerns the accessibility of test points. The Joint Test
Access Group (JTAG) formed in response to this challenge, resulting in IEEE standard
1149.1, the Standard Test Access Port and Boundary Scan Architecture.
The JTAG boundary scan test methodology allows complete observation and control of the
boundary pins of a JTAG-compatible device through JTAG software. A Test Access Port
(TAP) controller works in concert with the Instruction Register (IR); these allow users to run
three required tests, along with several user-defined tests.
JTAG tests allow users to reduce system debug time, reuse test platforms and tools, and reuse
subsystem tests for fuller verification of higher level system elements.
