JTAG Technologies delivered a broad line of software and hardware tools for test preparation, test execution, test result analysis, and in-system programming applications demonstrated the latest solutions at IPC Apex 2014. The company showcased the latest in its highly regarded range of boundary-scan controller hardware for PCB assembly and system testing– the versatile JT 5705 series. This completely new design concept incorporates both JTAG/boundary-scan controller functions and mixed-signal I/O channels. Extensive input protection is provided to ensure high levels of in-service reliability and low maintenance. Connection to the tester is via a USB interface. The first in the series – JT 5705/USB – is supplied as desk-top instrument, primarily aimed at hardware validation applications in design, small-scale production test and in some cases field service and repair. The JT 5705/USB features two 15 MHz TAPs and 64 I/O’s available through 0.1” IDC connectors. 56 of the I/O channels are always digital, 16 of which also feature a frequency function. The remaining 8 channels can be used as either digital I/O or analog I/O. The unit also contains a user programmable FPGA facilitating application specific digital I/O options. Via the built-in ‘Multi-Sync’ feature several JT 5705/USBs can be combined into a single JTAG controller providing multiple TAPs and hundreds of I/Os.
The second model in this new range is the larger JT 5705/RMI, a 1U high 19” rack-mountable instrument for use in systems or as a bench-top tester. This unit features four 15 MHz TAPs and 4 groups of 64 mixed-signal I/O channels providing a total of 256 I/O’s available through 0.1” IDC connectors. As before, within each 64 channels group, 56 channels are permanently digital with 16 available as frequency inputs. The other 8 channels of each group can be individually programmed as digital I/O or analog I/O channel. Furthermore the JT 5705/RMI features a total of 4 user programmable FPGA’s for creating application specific digital I/O options. The I/O capabilities as provided by the JT 5705/USB are also available in a separate I/O module, the JT 5112 Mixed-signal I/O scan module, or MIOS. The MIOS module can be used in combination with existing JTAG Technologies boundary-scan controllers such as JT 3705, JT 3710 and JT 37×7 adding analog I/O capabilities to those controllers.
Also on stage the JTAGLive CoreCommander – a simple, low-cost system that uses microprocessor core emulation modes to aid hardware validation and board (PCBA) testing. The easy user interface and low-cost JTAG interface hardware will enable users to construct read and write sequences from the processor core to embedded or external peripherals and peripheral controllers in minutes. Python support further enables users to construct more sophisticated test sequences using CoreCommander Python libraries as required – all from within the user-friendly JTAGLive environment. The JTAG ProVision software suite is used to generate boundary-scan tests and in-system programming applications for assembled PCBs and systems. This professional development tool is fully automated and supports the import of design data from over 30 different EDA and CAM systems. Jag’s acclaimed ProVision greatly simplifies the test engineer’s main task – to develop reliable tests with the best possible fault coverage for failures that may occur during PCB (printed circuit board) assembly.
