JTAG - Wikipedia
JTAG (named after the Joint Test Action Group which codified it) is an industry standard for verifying designs of and testing printed circuit boards after manufacture. JTAG implements standards for on-chip instrumentation in electronic design automation (EDA) as a complementary tool to digital simulation. [ 1 ]
What is JTAG? A guide to the IEEE-1149.1 standard - Corelis
JTAG is an integrated method for testing interconnects on printed circuit boards (PCBs) that are implemented at the integrated circuit (IC) level.
Technical Guide to JTAG - Corelis JTAG Tutorial
This JTAG primer provides a brief overview of JTAG devices--basic chip architecture, essential capabilities, and common system configurations.
High-level Guide to JTAG - XJTAG Boundary Scan
If a circuit contains more than one JTAG-compliant device, these can be linked together to form a JTAG chain. In a JTAG chain the data output from the first device becomes the data input to the second device; the control and clock signals are common to all devices in the chain.
Architecting a Multi-Voltage JTAG Chain | Analog Devices
This article compares several methods for designing a multi-voltage JTAG chain and provides tips and techniques for a robust, error-free design.
JTAG, commonly referred to as boundary-scan and defined by the Institute of Electrical and Electronic Engineers (IEEE) 1149.1, originally began as an integrated method for testing interconnects on printed circuit boards (PCBs) implemented at the integrated circuit (IC) level.
Figure 2 shows a basic JTAG chain consisting of JTAG-enabled devices connected in series through TDI and TDO. TCK, TMS, and TRST are com-mon to each device and are not shown. Th is chain is very simple and relatively easy to implement, but it is slow and does not provide focused testing. For example to access ASIC2, data must be serially shift-

What is JTAG boundary-scan?
JTAG/boundary-scan (IEEE Std 1149.1) is an electronic four port serial JTAG interface that allows access to the special embedded logic on a great many of today’s ICs (chips) .
access special test functions or configurations via JTAG that are not implemented in the debugger software. This training manual explains the basics of JTAG in case of a single TAP controller or several daisy-chained TAP controllers and how to perform a custom access to the JTAG port by using the TRACE32 software.
