JTAG - Wikipedia
WEBJTAG (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]

Introduction to JTAG and the Test Access Port (TAP)
WEBNov 18, 2020 · In addition, it specifies a test access port (TAP) which is a logic block responsible for executing tests and managing data flow along the boundary cells. The TAP, which is essentially a state machine and several shift registers, can be made to execute commands, like data load and data read.

WEBJTAG is defined as a serial communication protocol and a state machine accessible via a TAP. The DTAB (Debug and Test Access Block) is implemented on the target chip as a “passive” device that never sends data without request. …
WEBresult is stored in a JTAG register, all accessible via a fully 1149.1-compliant digital TAP. Figure 6 shows a block diagram of the SCANSTA476. Having the ability to add voltage measurement capability to a system through a JTAG chain is a powerful tool for the system designer. Differential Signals, AC Coupling, and JTAG
WEBJTAG Chip Architecture. The IEEE-1149.1 JTAG standard defines how IC scan logic must behave to achieve interoperability among components, systems, and test tools. ICs consist of logic cells, or boundary-scan cells, between the system logic and the signal pins or balls that connect the IC to the PCB.
