Abstrakt:

    The dissertation thesis is aimed at automatic delay faults test generation methods for digital systems. Path delay faults are tested via selected critical paths in a tested digital circuit. The critical paths can be specified e.g. by static timing analysis (STA), statistical static timing analysis (SSTA) and others. Signal delay propagation is also affected by many factors such as power supply noise, multiple input switching, temperature and others during test. The impact of each factor to the path delay faults has been individually solved and published in some papers but their joint effects should be also investigated.
    A new method for evaluation of critical paths and a general system for critical paths selection, named PaCGen, are presented in the dissertation thesis. The method is based on STA and influences of multiple factors used in the new technique for path criticality calculation. Some critical paths can be found as untestable based on structure of the circuit. The proposed system PaCGen includes also more effective DFT (design-for-testability) technique to change untestable critical paths to testable. Evaluation of the proposed method, system and used techniques has been done over selected benchmark circuits and compared with published results.
