Boundary-scan news at Electronica

Electronica 2006 offered opportunities for Goepel to launch IEEE 1149.6 support integrated within its System Cascon software, while XJTAG demonstrated its new XJTAG Professional development system. In addition, Asset InterTech and JTAG Technologies highlighted products they had demonstrated at last month’s International Test Conference.
Goepel electronic announced that it has added to its System Cascon boundary-scan software platform tools that support of IEEE 1149.6. The integrated tools support dot-6 database management, automatic test-program generation (ATPG), automatic fault diagnostics, graphical fault localization, and debugging.“We incorporated the skills from more than two years of dot-6 application practice with customer projects directly into the further development of our system software. On this basis we are able to provide an industrially proven and extremely powerful IEEE 1149.6 tool,” explained Thomas Wenzel, managing director of Goepel electronic’s boundary-scan division. “In particular, the complete automation of all necessary timings for control sequences allowing for all imaginable IEEE 1149.1/IEEE 1149.6 applications enables an unrivalled ease of use. Users are now free from time-consuming manual improvements and do not need to code the fine details. At the same time we improved the acceptance of this standard particularly ground breaking for the test of modern high-speed interfaces in BGA packages.”
The enhanced IEEE 1149.6 tools allow transparent process cycles and a clearly structured data flow. As first step, an intelligent project data base including all 1149.1 and 1149.6 structures, differential channels, and AC couplings is generated by means of the graphical component library. The system can import IEEE 1149.6 BSDL files and export verified BSDL files for use in ATE. Based on this data the enhanced ATPG for 1149.1/1149.6 interconnections generates a commented and editable source code in the system’s boundary scan programming language, Caslan. From this the tool automatically generates all required timing settings by using dynamically adapted TCK frequencies. The ATPG supports pure and mixed dot-1/dot-6 DC/AC connections as well as advanced DC Tests.
If required, source code can be executed stepwise via an integrated multi-mode debugger. Compiled test programs are cross-compatible with all Goepel boundary-scan controllers. To speed physical fault location, users can visualize faults in the integrated ScanVision layout viewer.
