Purpose of jtag

WebJTAG Programmer software uses sequences of JTAG instructions to perform the following programming and verification operations. The user need only select the desired operation; the software will execute all required JTAG commands transparently. For a description of JTAG instructions supported by Xilinx devices, see Appendix A. WebDec 21, 2024 · Beyond the JTAG Master, the other main component of any at-scale debugging solution is the run-control library. Written in ‘C’, the run-control library provides the API to program the interface at an x86 architectural level, as opposed to solely at the JTAG state move and instruction register/data register scan level.
