goJTAG is the first university-driven open-source project aiming at providing a full package for a JTAG newcomer including training materials, slides and exercises. The software includes a simulation component that fully illustrates the underlaying concept of JTAG/Boundary Scan. The user can directly step-wise control the test features of IEEE 1149.1 compliant devices and observe a system’s reaction in a real time in an on-screen simulation. Using a PicoTAP controller, all actions can be applied to a unit under test (UUT) it is connected to. Such a fine-grain illustration of JTAG test principles has not been possible until now.
