Discover a World of Boundary Scan & JTAG Benefits

Do you wish that you had the ability to debug your prototype and pinpoint defects earlier in the design stage? Have you ever wanted precise fault data during manufacturing that could be incorporated into process improvements? Would you like the flexibility to perform in-system programming of logic and flash devices to expedite production and decrease inventory? Do you want a way to dramatically reduce no-fault-found problems - where the board fails in the field, but works at the repair station? JTAG, or as it is known by its official name, IEEE 1149.1 boundary scan, is your answer.

The underlying purpose of JTAG or boundary scan technology is to enable engineers to overcome the limited access challenges of today's complex boards by providing virtual access to the board. But the best thing about the IEEE 1149.1 boundary scan standard is the enormous business benefits it delivers.

Reduced time to market. Reduced risk. Increased quality. Decreased defects. Increased productivity. Lower inventory levels. Less waste and board damage. The convenience of reprogramming without disassembling boards. The expediency of reusing the same 1149.1 tests from design to manufacturing and repair. In addition to saving costs by not requiring fixtures, JTAG / boundary scan tests can be executed on a low-cost PC platform.

Boundary scan technology gives you the power to create these benefits and more. And ASSET's boundary scan environment, ScanWorks, gives you access to everything you need to make it happen
