Dive deep into the architecture of the JTAG TAP (Test Access Port) Controller — the central finite state machine that powers modern chip debugging, boundary scan testing, silicon bring-up, and DFT infrastructure.
This video explains how the 16-state TAP controller operates internally at RTL level, how TMS controls state transitions, and how instructions/data are shifted through IR and DR scan paths using TCK-driven serial communication.
