WebJTAG is commonly referred to as boundary-scan and defined by the Institute of Electrical and Electronic Engineers (IEEE) 1149.1, which originally began as an integrated method … JTAG (named after the Joint Test Action Group which codified it) is an industry standard for verifying designs 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. … See more In the 1980s, multi-layer circuit boards and integrated circuits (ICs) using ball grid array and similar mounting technologies were becoming standard, and connections were being made between ICs that were not available to probes. … See more In JTAG, devices expose one or more test access ports (TAPs). The picture above shows three TAPs, which might be individual chips or might be modules inside one chip. A … See more Microprocessor vendors have often defined their own core-specific debugging extensions. Such vendors include Infineon, MIPS with EJTAG, and more.
