Boundary Scan Coach Description:
- How to stimulate and observe board- and system-level interconnects with Boundary Scan?
- How does the Test Access Port (TAP) work?
- How does the serial transmission of test pattern work?
The interactive learning software Boundary Scan Coach provides answers to these and many more questions. This tool illustrates how Boundary Scan test resources can be accessed, and how they can be utilized for structural interconnect testing. Boundary Scan vectors can be applied to a Unit Under Test - either virtually or on a real board - to demonstrate the IEEE1149.1 principle!
The Boundary Scan Coach software is organized in two sections:
- Boundary Scan Basics - The user is introduced step by step to the basics of the JTAG/Boundary Scan/ IEEE1149.1 technology. Among other things, it is demonstrated how an instruction (e.g. BYPASS) can be loaded into a Boundary Scan device (IRShift), and how the level on a Boundary Scan pin can be read (DRShift).
- Learning by doing - Just as the name indicates, this section allows the user to interact with a virtual or a physical board to apply the Boundary Scan methodology. The various Boundary Scan modes (Instructions EXTEST, BYPASS, SAMPLE, ...) are graphically illustrated on the screen. When the optional BScan Coach Board is connected to the PC, the test methodology is not only explained in the software but can also be experimented with on a real [hardware]. This makes the learning experience more fun while enhancing the understanding of the principles specified in IEEE-Std.1149.1.
