In this study, we propose combining regular expressions, FSM, and graph traversal techniques to construct a systematical test pattern generator.
Usually fault simulation inspects whether all undetected faults are detected by a test pattern. The list of the inspected faults is very large for complex circuits.
A high-level fault dictionary is generated for the given test where for each test pattern it will be shown in which modules the defects may be detected by this pattern.
The collaboration with Belgium-based Imec (www2.imec.be) provides design-for-test (DfT) and automatic test pattern generation technology said to ease testing of 3D-ICs with through-silicon via (TSV) functionality.

A color-bar test pattern on the screen casts a gently moving rainbow on the wall as an elderly Englishwoman holds forth on various methods of high-speed typing, perfume, and, predominantly, the BBC Radio 4 programming--plays, the news, the shipping forecast, Women's Hour--that is her daily companion.
Before a boundary scan test pattern can be automatically generated by a test system (see Figure 2 for the configuration of a typical boundary scan test or programming station), boundary scan devices on the board and the scan path must be characterized.
