ASTA-an integrated system for BIST analysis & automatic test generation

The automatic self test analysis (ASTA) tools are an integrated part of the ICL DA-X system. ASTA analyses a design for self-testability, automatically generates chip test data, calculates signatures and outputs tester format data. Tests for primitive logic will be exhaustive or quasi-exhaustive, but for larger cells, specific test methods can be defined using an ASTA language. The system, which is Esprit-funded, has been used successfully for two complex ASIC chips.<
