JTAG Technologies will showcase its latest hard- and software solutions at Embedded World Show in Nuremberg. AutoBuzz, the latest tool from JTAGLive family, effectively learns a connectivity signature of all boundary-scan parts within a design from only the BSDL models of those parts. By expanding on the seek and discover mode of BuzzPlus, AutoBuzz automatically gathers the circuit data of a known good board and then performs a full connectivity compare against the faulty circuit. AutoBuzz supports just two simple operating modes: Learn and Compare. With AutoBuzz in Learn mode a ‘known good’ sample PCB is initially scanned to establish a reference connectivity map. Suspected faulty boards can then be scanned by AutoBuzz in Compare mode, and a comparison is automatically made of their connectivity maps. Differences between the two maps are highlighted to indicate possible faults such as interconnect short-circuits, open-circuits or ‘stuck-at’ faults. Since the user requires no boundary-scan technical knowledge and with only a basic scan chain input needed, AutoBuzz is the perfect tool for repair and rework technicians, especially when design data is missing or incomplete.
In co-operation with the Benelux regional representative of Altium - Transfer BV - and hardware development consultancy – DsignWorx BV - the new JT 2155 training board has been devised to demonstrate all the latest features and test techniques available to users of JTAG Technologies’ ProVision & JTAGLive application development systems. For Altium users the design serves as an example of how to adapt the feature-rich Nano board into a realistic custom design. Key features of the JT 2155 are ARM 7TDMI Core NXP processor, Altera Cyclone 3 FPGA, DDR2 memory block, Serial I2C memory, ADC, accelerometer, touch screen controller. The new training board has been built to to show exactly what JTAG/boundary-scan is capable of in the second decade of the 21st century.
