Abstract :
An automatic test pattern generation (ATPG) method is presented for a scan-based test architecture which minimizes ATE storage requirements and reduces the bandwidth between the automatic test equipment (ATE) and the chip under test. To generate tailored deterministic test patterns, a standard ATPG tool performing dynamic compaction and allowing constraints on circuit inputs is used. The combination of an appropriate test architecture and the tailored test patterns reduces the test data volume up to two orders of magnitude compared with standard compacted test sets
