Boundary Scan Coach
Interactive Boundary Scan learning software for IEEE 1149.x
- 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
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 Boundary Scan 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.

In principle, the Boundary Scan Coach works without additional hardware. In that case, the software runs in virtual mode. However, an optional demonstration board - the "Boundary Scan Coach / EZScan Board" - can be used to apply and illustrate the principle of Boundary Scan on a real hardware. In addition to the Board, a Boundary Scan Controller is needed for the connection to the PC.
The "Boundary Scan Coach / EZScan" Board is a printed circuit board used to demonstrate the Boundary Scan test methodology. The boards simplicity ensures a quick and fun learning experience. Two small PLD's (from ALTERA and XILINX) with JTAG / Boundary Scan / IEEE1149.1 resources, a SRAM, a Flash EEPROM, and Buffer and Logic Cluster devices provide the variety of components needed to experiment with the different types of Boundary Scan applications.
JTAG/Boundary Scan Controller
To apply the Boundary Scan pattern to the Unit Under Test and to read test results, a Boundary Scan Controller is needed. The Boundary Scan Coach supports all [Boundary Scan Controller] from GOEPEL electronic as well as programmer hardware (for Parallel Port only) from ALTERA, LATTICE, and XILINX .
