Mining systems innovator ups the pace with XJTAG Boundary Scan

When South African mining technology pioneer DetNet chose to implement boundary scan test throughout development and production, to boost productivity and increase test coverage, the company’s engineers scrutinised the leading platforms on offer to select the system offering the best features, usability, and customer support. XJTAG was the clear winner.

DetNet’s engineers have evaluated a number of boundary scan systems extensively, seeking a cost-effective and easy-to-use platform to help accelerate testing and debugging of new boards and get first prototypes up and running quickly. “XJTAG has all the features we need, and the graphical interfaces such as XJAnalyser help make it the easiest system to use. We knew we could become productive very quickly using XJTAG”, comments Abrie Liebenberg, Senior Development Engineer at DetNet. “The high quality of customer support provided, both directly from XJTAG and via our local distributor, ASIC Design Services, helped finalise our decision.”

XJAnalyser is a graphical application that helps engineers interact with the circuit under test. It helps speed up debugging, and can program devices with SVF and STAPL files thereby saving the cost of additional programming tools.

By providing a graphical view of the boundary scan chain, XJAnalyser enables engineers to visualise the circuit and set or toggle individual pins to trace any problems such as shorts or opens.

The XJTAG platform also includes the XJDeveloper test development environment, which helps setup and run tests on the circuit. Common tests such as connection tests and memory tests are built in, and XJDeveloper also facilitates storing and reusing tests throughout product design and manufacturing, as well as in subsequent projects. This saves considerable time and development effort.

“Features such as XJAnalyser have helped us to save time and significantly increase test coverage from the early stages of product development”, confirms Abrie Liebenberg. “We can isolate faults quickly and precisely thanks to colour-coded graphics, and we can also test BGA connections with a higher level of confidence than ever before.”

DetNet is also using XJTAG as part of its production testing schedule, taking advantage of the XJRunner system, which is optimised for use on OEMs’ or contract-manufacturers’ production lines. XJRunner enables simple, secure and audited testing and allows bootloader programming. Features include graphical schematic and layout viewers, support for batch testing using multiple XJLink connections or the four-port XJQuad, and tools to help analyse board statistics and fault trends.

“The outstanding customer support provided by XJTAG has been key to helping us achieve the best possible performance from the system”, adds Abrie Liebenberg. “When we wanted to use it for checking ADC measurements, XJTAG’s engineers responded by writing a unique software test for us to use. That level of care reinforces my opinion that we made the right decision to go with XJTAG.”
