Satellite Ground Systems Meet Sky-High Targets, with XJTAG Boundary Scan “


Kongsberg Spacetec AS, based in Tromsø, Norway, is a leading provider of satellite ground station systems for earth observation satellites. The company provides turnkey systems as well as specialised solutions for environmental and meteorological surveillance, such as sea-surface temperature measurement, cloud analysis, oil-spill analysis, or ship detection. Spacetec also provides customer services including systems engineering, training, maintenance and support.


The ground station systems


perform functions such as signal processing, communication and networking, and use high- performance servers featuring PCI cards designed by Spacetec’s electronic engineering team. The server cards use high-bandwidth standards such as PCI-X and PCI Express, and include multiple high- performance processors, FPGAs, and high-speed FIFOs and RAMs. The boards are extremely complex and densely populated, and present tough test challenges from the beginning of design through to final production. Many of the devices are housed in BGA or chip- scale packages that cannot be probed or visually inspected.


“We are using boundary scan


tools early in the design phase to assess the testability of our boards, and to help with any design changes necessary to reach our test coverage targets,” explains Øyvind Undstad, one of Spacetec’s electronic designers. “The XJTAG system provides the capabilities we need at


a very competitive price, and is very easy to use. Initially, the time to get the system up and running, and performing productive tests, was a matter of hours; other systems can require a few days’ effort.”

detection, and a large library of tests for standard parts. XJTAG’s high-level test description language, XJEase, delivers the flexibility of a programming language, such as loops, variables and flow control, for engineers developing device and circuit tests. Tests can also be re- used in subsequent projects, since device tests written in XJEase are independent of the specific circuit under test.


” “XJTAG helps us assess each


design at an early stage, by supporting design verification and DFT analysis,” continues Øyvind Undstad. The built-in Design For test (DFT) feature allows engineers to see the board’s test coverage, while the advanced connection test helps pinpoint errors and is able to test a

XJTAG is also in action at


Spacetec’s manufacturing partner, Noca AS, which has several XJRunner stations on its production lines. Øyvind Undstad explains, “We provide boundary scan tests for the Noca team to use directly on XJRunner. These include interconnection tests, RAM tests, and simple functional testing of non-JTAG components, as well as programming of Flash memory. Most assembly defects can be identified at manufacture and repaired immediately. This avoids having the boards shipped back to us for fault finding by our engineers, which saves valuable time and helps increase productivity.”
