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.

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,.

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 board is always an option. However, developing a test that takes into account […]

That’s an easy one. With onTAP’s TAP CONNECT JTAG Controller, you can run an unlimited number of chains simultaneously. Each TAP CONNECT JTAG Controller has two channels which provides the opportunity to run two chains at once. Furthermore, additional chains are handled with ease by additional Controllers. In fact, there are no restrictions on the […]

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 associated with the test access controller, e g., the TAP […]

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 there are several things that are needed: a netlist of the […]

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.
