Beyond the Boundary Scan Test: Testing for Mid-State/Resistive Shorts

Beyond the Boundary Scan Test: Testing for Mid-State/Resistive Shorts

Mid-state shorts are a major problem that often goes undetected by typical boundary scan connectivity tests is mid-state/resitive shorts. Flynn Systems recognized this “hole” in boundary scan testing and was the first boundary scan test company to test for mid-state shorts, improving test fault coverage.

What Is a JTAG Test and Why You Need to Know

What Is a JTAG Test and Why You Need to Know

Formed in 1985, Joint Test Action Group (JTAG) developed a method of verifying designs and testing printed circuit boards after manufacture. This method would later become the industry standard. Known as a JTAG test,.

How Test Developers Can Save Their Company Time and Money

How Test Developers Can Save Their Company Time and Money

If a chain of devices consisted only of boundary scan (JTAG) compliant devices, there would not be too much testing required. However, boards today contain complex, non-JTAG devices that interact with the boundary scan devices. Testing just the JTAG devices on the...

Why Bother with JTAG?

Are you new to boundary scans and JTAG? Take a look at this quick guide to understanding what exactly it means, and why JTAG is essential. JTAG stands for Joint Test Action Group. When referred to as part of a boundary scan test, it means computer chips and electronic...

Finding Faults with the Test Access Port (TAP)

Finding Faults with the Test Access Port (TAP)

Once a board developer passes along the new board and all related files and procedures to a test developer, the boundary scan test process can begin. We recommend including the TAP Integrity Test at the beginning of your interconnect test because the TAP contains pins...

Testing Multichip Modules

Testing Multichip Modules

Chip manufacturers are now producing multichip modules (MCMs) that may include two or more arrays of devices within a single package. These modules can be tested using JTAG test pattern generation of the devices while on a PCB. To incorporate JTAG testing of MCMs...

Whose Problem Is This?

Who cares. The owner of the problem is not necessarily always the issue. Blame most often gets thrown around the work place when things don’t work, and a resolution is needed.

How much money is sitting in the bone pile?

One of the most common comments we hear from our customers and business partners sounds something like this: “Well, I’ve heard about boundary scan testing, and have actually used it a bit before. Moving forward, we have a new project we need to use it on, and we have a bone pile I might get to.”

Manufacturing: Save Yourself, & The Project, Lots Of Money!

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.

SVF and onTAP Boundary Scan

Why SVF? As boundary scan test was making its way to center stage for testing surface mounted devices, there was no agreed upon protocol to manage the hundreds of thousands of bits of IEEE 1149.1 test pattern information. Instead, many vendors had vendor specific...

A Quick Reference Guide to Boundary Scan Terms

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...

New To JTAG Boundary Scan Test? You’re not alone…

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...

JTAG.TECT Delivers onTAP to Russian Customers

Current and potential customers of onTAP Boundary Scan Solutions, and onTAP Series 4000 are able to use some of StarTest’s hardware and software solutions (DIMM/SODIMM External Modules, TAP Distributor and Bridge-For-Testability hardware tools, Operator Fault Spotlight software tool), as built-in features of the onTAP Boundary Scan Solution, usable throughout the users’ product lifecycle, including volume manufacturing and in-the-field troubleshooting and repair.

onTAP BIST (Built In Self Test)

Tests may be defined in script files which may then be translated into executable Serial Vector Format (SVF) files. The general approach is to place all of the required BSDL files into a folder and then to relate the BSDL files to circuit locations in declarations at...

PC Based Parallel Test

Ontap_parallel.exe can be used to simultaneously run test suites on multiple PC boards using the onTAP DLL. Parallel board testing must be enabled for the DLL license. Testing is fastest on a multiple processor PC , particularly where one core processor is available for each board. For example if four PC boards are being tested in parallel, then a quad core processor is recommended so that the time to test four boards is about the same as that required to test one board.
