Boundary Scan Test

Now that your board has moved from prototyping to manufacturing, things are humming along until…there is a snag in manufacturing. Suddenly an entire run of boards is failing for unknown reasons, and you’re already dangerously close to being behind schedule.

Use this function to: Check the fault coverage of your test for a specific fault condition. Insert an open fault without modifying your board or test fixture. Validate that your test is working as expected. How to Insert Faults 1. Create a file FaultInsert.txt in your test project directory. 2. Add fault declarations to the […]

While not all boundary scan terminology is contained in the guide, there are enough terms to at least acquaint you with some of the most commonly used expressions. BIST: Built-In Self-Test, sometimes controllable via boundary scan BOARD NETLIST: Files that show the connections between devices on a circuit board and the probe access to circuit […]

Many newcomers to JTAG test start their first projects knowing only that boundary scan testing is a requirement for new board design. The specifics of boundary scan, details of test strategy, or expected results are, for many, uncharted territory. In fact, most newcomers to boundary scan testing are uncertain as to what questions to ask […]
