place high importance on testing to ensure the best possible quality and – ultimately – safety. XJTAG boundary scan is an important part of their test strategy, offering powerful features, flexibility and high-quality support at a competitive price.


NRPL Group seeks out XJTAG Boundary Scan for radar “





NRPL Group is a Finland-based specialist in radar for air-traffic control, and has group companies in Czech Republic and Russia. Its products include Primary Surveillance Radar (PSR), Monopulse Secondary Surveillance Radar (MSSR) and advanced Automatic Dependent Surveillance-Broadcast (ADS-B) solutions, as well as radar data processing and distribution systems, air traffic control and management systems, voice and data recorders. The company also supplies associated systems and sub-units such as radio equipment and signal and data processing systems.


Rigorous testing of all boards and


systems is extremely important, from early design verification through prototyping and testing production units. “Radar is essential to the safe, efficient operation of an airport. It is absolutely vital for us to ensure total dependability of all systems before shipping to our customers,” comments Reidar Gjerstad, Senior System Engineer at NRPL’s main Finnish site at Vantaa. His team is using boundary scan as part of the strategy for testing prototype and production radar-controller boards, and XJTAG is the chosen solution.


“Writing tests using XJTAG and


executing them via the boundary scan port is faster than other methods for testing our boards,” explains Reidar Gjerstad. “XJTAG really helps to speed up our prototyping activities by allowing us to assess any new digital circuitry within minutes.”


Another key benefit of using XJTAG is that engineers can begin


preparing tests for a board before the prototype hardware is built, enabling faster development. “We can start writing tests straight after the netlist is generated, which means we can be ready to test the first prototypes as soon as they arrive,” adds Reidar Gjerstad. “Also, writing test scripts is easy, using the high-level XJEase language, and

many scripts for standard non-JTAG devices are already available from XJTAG or can be easily modified from existing code.”


The XJTAG system also provides


the flexibility to test analogue circuitry within the boundary scan test environment. NRPL is taking advantage of this to test various ports and check power supply voltages. “By building a simple adapter containing a DAC or ADC, we can use XJTAG to generate analogue test voltages or check the voltage on various pins such as power supply outputs and analogue ports.”
