Feature size reduction drastically influences permanent faults occurrence in nanometer technology devices. Among the various test techniques, Software-Based Self-Test (SBST) approaches have been demonstrated to be an effective solution for detecting logic defects, although achieving complete fault coverage is a challenging issue due to the functional-based nature of this methodology. When VLIW processors are considered, standard processor-oriented SBST approaches result deficient since not able to cope with most of the failures affecting VLIW multiple parallel domains.
