The boundary scan test software provides a way to interconnect between integrated circuits (ICs) on a board without using physical test probes. The scan contains cells within a device that can capture data from pin or core logic signals or force data onto pins. The captured data is moved out and externally compared to other […]
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 […]
Today’s consumer is provided a variety of options no matter what the subject matter happens to be. At Flynn Systems we like to keep things simple by providing the best solution in boundary scan options. Saving the consumer both time and money by avoiding trial and error software, Flynn’s boundary scan is no nonsense and […]
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 […]
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 […]
Not every boundary scan application experiences delays. Some run without any problems, but when there is a delay, oftentimes it can be traced back to lack of information from the board’s developer to the board’s tester.
