Within the framework of the goJTAG initiative, Goepel Electronic has developed a new demonstration kit. In addition to the USB 2.0 controlled Boundary Scan controller PicoTAP and respective software, it contains a specific demo board for practical exercises.

The networking founded by various universities and the Company Testonica Lab, pursues the goal of providing the industry JTAG/Boundary Scan tools and knowledge based on an independent and non-commercial platform, sustainably accelerating the wide adoption of standardized IEEE 1194.x test methods. The centerpiece of Goepel Electronic’s engagement is the provision of free hardware and respective reference designs.

The open-source project goJTAG provides IEEE 1149.1 training software that can be run in both simulation mode as well as online mode. The tool enables numerous graphical displays on various levels. In the online mode users are able to utilize the software for the new demo board for individual projects without restrictions. Additionally, the goJTAG software includes simulation components that fully reveal every single bit of movement along the scan chains with a single TCK precision. Hence, users are able to step-wise control TAP states and observe system's reaction in real time as an on-screen simulation. Such a detailed illustration of JTAG/Boundary Scan test principles has not been possible so far.

The source code written in JAVA is freely accessible and can be changed under the general terms and conditions for open-source software. Furthermore, the reference designs for the specifically developed controller PicoTAP and the new demo board are available for non-commercial applications free of charge.
