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,.

When large numbers of outputs switch simultaneously, they can cause intermittency with your test due the ground bounce effect. JTAG Test with onTAP lets you control this problem by giving you control over how many outputs switch during a single test scan, as shown below: Understanding ground bounce In manufacturing test environments, it’s not […]
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 devices that are made according to […]
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 […]

We are constantly exposed to new situations in boundary scan test and new approaches to using boundary scan to achieve better test fault coverage. One item standing in the way of higher, more accurate fault coverage is common tri-state control cells.
