Diploma Work - Boundary Scan Testing on Student Built PCB

The goal of this application is to familiarize our students with the principles of the IEEE Std. 1149.1, commonly adopted in industry terminology as Boundary Scan Testing (BST).
A Boundary Scan Test is implemented for a test board containing 3 controllers and peripherals. The main focus is the simulation and auto-testing of the communication between two individual control units.
The XJLink2 (from XJTAG, www.xjtag.com/about-jtag/) controller performs the main BST procedures defined via XJDeveloper. The Digilent Analog Discovery 2 (AD2, from Digilent) is used for accurate frequency and voltage measurements and for interactive connector validation.
What have we learned/gained:
- What is the purpose of BST, the advantages and challenges when compared against other industrial test technologies;
- The design guidelines and requirements for IEEE 1149.1 enabled electronic boards;
- The ability to design, build and verify a simple electronic board, using dedicated industrial tools;
- The ability to implement a functional BST project and present initial coverage analysis data;
- The ability to extend test coverage on their board by using additional measurement tools, in compliance with diploma requirements.
