As well as displaying live data, Waveform Viewer also supports triggering, allowing circuit behaviour to be captured under specified conditions, such as when particular events occur. This can greatly improve an engineering team’s ability to capture key information and track down intermittent faults.Through the flexibility of JTAG it is possible to observe and capture run-time functionality, even under BGA devices where pins are not accessible to a standard logic analyser. Waveform Viewer also supports the same pin driving and toggling functionality offered in Chain View within XJAnalyser, allowing engineers to drive signals from JTAG and observe the rest of the board, ensuring it responds as expected. XJTAG v3.4 also improves support for JTAG devices that feature multiple JTAG cores, such as advanced Microprocessors, specialist SoCs and ASICs. Using multiple JTAG chains allows more complex tests to be executed and by improving its multicore support.XJTAG’s production test environment, XJRunner has also been improved with greatly enhanced logging capabilities. The new enhanced format means log files can now contain the full details of errors, complete with links to the Layout and Schematic Viewers, which can be viewed long after the tests were carried out.Other improvements in XJTAG v3.4 include enhancements within XJDeveloper that increase usability and speed project setup. These include improvements to the suggestions automatically made for Power and Ground nets, and to the formatting of project errors and warnings, which now include helpful links to direct the user’s attention to the right place in the project. XJTAG www.xjtag.com Hybrid sensor spots cable fires before they start burning Scientists of KIT and Karlsruhe University of Applied Sciences have developed hybrid sensors that can detect smoldering cable fires at an early stage by analyzing the plastic vapors released by overheated insulating cables. The novel sensors combine measurement processes with data evaluation and the research is reported in the Sensors & Transducers Journal. A smoldering cable can be detected with a little luck before it starts burning: the plastic coating changes color, there is a smell of burning. Hybrid sensors might detect the risk of cable fires earlier, even before they are perceived by eyes and nose. They detect the gases released from the plastic coating due to heating and reliably identify and analyze the gas mixture and its concentration. In addition, they can also detect interfering gases, such as propene or carbon monoxide, and, hence, exclude false alarms. To this end, the hybrid sensors do not only possess a gas-detecting sensor chip, but also the computation capacity and algorithms needed for evaluating measured data. The sensitive and reliable hybrid sensors might increase safety in cable ducts. In addition, their capability of finding gas mixtures and determining individual gas concentrations might be useful for detecting toxic mold gases during food control, explosive gases in fertilizer silos, or leaks of natural gas pipelines. www.electronics-eetimes.com Electronic Engineering Times Europe December 2015 43
