Curtiss-Wright


off-the-shelf (COTS) systems and board level products, is using the XJTAG boundary scan development system to improve the process of debugging and testing its range of radar, video and graphics products.


Curtiss-Wright’s video and graphics group designs rugged and benign solutions for customers across the defence, aerospace, commercial and industrial marketplaces. Its expertise encompasses radar pre-processing, scan conversion, tracking and display integrated with TV video, infra-red and sonar, as well as compression, decompression and distribution of radar and TV video across wide and local area networks.


The group’s products and solutions


are used throughout the world in vehicle, airborne and shipborne command and control consoles, vessel tracking, air traffic control and air defence systems. Customers include, among others, BAE Systems, Boeing, DRS Technologies, EDO Corporation, Lockheed Martin, Northrop Grumman and Raytheon. Faced with the challenge of


improving the process of debugging and testing its latest range of highly complex ball grid array (BGA) populated printed circuit boards, engineers at Curtiss-Wright’s video and graphics group in Letchworth, England, set out to find a cost- effective boundary scan solution. “We selected the XJTAG system


due to its price, the speed and accuracy of fault diagnosis, and because the re-usable test scripts can be ported from project to project and migrate through design, prototyping to production and beyond,” said Alan McCormick, managing director of Curtiss-Wright’s video and graphics group.


XJTAG is now being used to debug and test products such as


Curtiss-Wright’s Sabre imaging platform, which combines a high- performance PowerPC processor with a multi-head, multi-layer graphics video and radar display capability in a single VME slot. It is also being utilised on the Osiris dual-channel radar interface board. “Using XJTAG, we are able to very


quickly debug and test both the boundary scan and cluster devices on our Sabre and Osiris boards, many of which are inaccessible to traditional


opinion


test methods such as flying probes, logic analysers, oscilloscopes and X-ray systems,” added Stuart Allen, senior hardware engineer at Curtiss- Wright’s video and graphics group.


XJTAG enables engineers to test a


high proportion of the circuit including BGA and chip scale packages, such as SDRAMs, Ethernet controllers, video interfaces, Flash memories, FPGAs and microprocessors. The ability to test both boundary scan and cluster devices gives engineers valuable extra flexibility to design tests for critical parts of the board.


“We are using FPGAs on many of


our cards and with the XJTAG circuit visualisation tool (XJAnalyser), we can read and write to all the thousands of

due to its price, the speed and accuracy of fault diagnosis, and because the re-usable device-centric test scripts can be ported from project to project and migrate through design, prototyping to production and through into field test roles. Using XJTAG, we can very quickly debug and test both the boundary scan and cluster devices on our boards, many of which are inaccessible to traditional test methods such as flying probes, logic analysers, oscilloscopes and X-ray systems.


“We selected the XJTAG boundary scan development system ” Advertorial


device pins on an FPGA or another JTAG-enabled device and validate that every pin is functioning whether or not it is being utilised in the first release of the product or not,” added Stuart Allen, “this capability is very valuable.”


” The XJTAG development system is


a cost-effective solution for debugging, testing and programming electronic printed circuits boards and systems throughout the product lifecycle. The XJTAG system reduces the time and cost of board development and prototyping by allowing early test development, early design validation of CAD netlists, fast generation of highly functional tests and test re-use across circuits using the same devices.
