Open source project to provide boundary scan tools in non-commercial platform

Goepel electronic has launched an open source initiative to provide JTAG (joint test action group) and boundary scan tools based on an independent and non-commercial platform. The goJTAG open-source project aims at providing a full package for JTAG and boundary scan tools by including training materials, slides and exercises. The software includes a simulation component that reveals every single bit movement along the scan chains with a single technology compatible kit precision. The company claims that users can directly step-wise control TAP states and observe the system's reaction in real time as an on-screen simulation. Using PicoTAP controller, all actions can be synchronised on the hardware attached.

The open-source project provides IEEE 1149.1 training software that can be run in simulation mode as well as online mode. The tool enables the graphical display of boundary scan ICs in the respective mode, the visualisation of register states, pin toggling and the execution of simple vector format files without qualitative limitations. In the online mode, the software can be utilised for individual projects. For this purpose, the company has developed a specific controller, which is also available as a reference design.
