The basis of the hierarchical test concepts are component test programs that are a constant part of the complete system, and are administered by complete device libraries. These models are easily exportable to other stations. The test programs itself are defined by Source Code in CASLAN (CAScon LANguage). This specialised Boundary Scan programming language with more than 250 commands, enables algorithmic vector generation, adaptive fault diagnosis, interactive user communication, mixed signal test and file handling.
