Trainer 1149: a Boundary Scan Simulation Bundle for Labs

This paper presents a software/hardware bundle for studying, training and research related to IEEE 1149.1 Boundary Scan (BS) standard. The presented package includes a software environment that is capable to graphically visualize BS facilities and perform fine-grain simulation of BS test process. The system is not restricted to the limited number of examples but rather provides user with a full flexibility in working with any type of BS structures. For that, the software supports standard formats such as Boundary Scan description language and SVF (for defining test patterns). A special fault simulation mode allows injecting various types of interconnection faults and simulating their impact. The bundle also incorporates a low-cost USB-JTAG cable that can be used to run the experiments on real hardware. The software part is implemented in platform-independent Java environment and is distributed as a freeware.
